Important Questions Answer

Knowing process involves a series of mental functions like sensation, perception, conception and thought. Theses knowing processes of human mind involve a series of well organised psycho-physical functions that give a clear picture of our cognitive domain.

Sensation

1. What is Sensation?

Ans: Sensation is the simple and elementary form of consciousness or a physical awareness of the situation, which does not bear its clear meaning. It may said as the preliminary state of mind.

2. Give one definition of Sensation.

Ans: According to Warren Brown and Howard Gilhousen, “A sensation is an awareness of the bare quality of experience and rises directly from the stimulation of sense organ”.

3. What are the two conditions necessary for getting sensation?

Ans: The two conditions necessary for getting sensation are:

(a) Receptive ability of the sense organs to deprive impression out of the stimuli.

(b) Adequate stimulation of the external object.

4. What are the two sources of Sensation?

Ans: The two sources of sensation are:

(a) Internal. (Internal parts like stomas, intestines and muscles).

(b) External. ( like visual, auditory, tactual, olfactory and gustatory).

5. Can there be sensation without sense organs? Briefly explain.

Ans: Yes, there can be sensation without sense organs because there are two experiences of sensation. One is external and another is internal. External sensation react to external stimulation experiencing like visual, auditory, tactual, olfactory and gustatory senses. Internal sensation refers to internal parts of the body like stomach, intestines, and the muscles which do not have special experiences such as hunger, thirst, fatigue, head ache, etc.

So, it is evident that sense organs are not the only ways and means of getting sensation.

6. Write four characteristics of Sensation.

Ans: The four characteristics of sensation are mentioned below:

(i) Sensation is the simple physical experiences or bodily impression received from the environment.

(ii) Sensory experiences are fixed so far as the specific sense organs are concerned. One organ can not work for the other.

(iii) Sensation depends upon receptive capacity of the receptor cells and transmitting ability of the sensory and motor nerves of the organism.

(iv) Adequacy of sensation depends upon quality, intensely, duration, and clearness of the object in environment.

(v) Sensation is objective mental state, as it depends on stimulus.

(vi) Sensation is the simplest and the most elementary mental process.

7. What are types of Sensation? Explain briefly.

Ans: Accordingly sensation may be classified into three types namely,

(a) Organic Sensation:

It refers to the biological needs which bring about psychological changes in the internal part of the body of the organism. The sense of hunger, thirst, indigestion, vomiting, stomach pain, headache, suffocation, etc. are the organic sensation experienced. They do not have specific sense organ to be located. They effect the body in general.

(b) Special Sensation:

It refers to the specific five sense organs of the body. Their experiences of sensation are colour(vision), smell(olfactory), sound(auditory), taste(gustatory), and heat and pressure(tactual). Every kind of sensation is received by the specific sense organ out of the specific stimulus. Therefore, this kind sensation is also known as the gateways of knowledge.

(iii) Motor or Kinaesthetic Sensation:

This kind of sensation is experiences in the voluntary muscles, tendons and joints due to motor movement. Such experiences are contraction, pulling or pushing due to repeated physical activity which is known as motor sensation. This type of sensation is also quite vague that can not be clearly explained and distinctly localised on the body.

8. Write two educational significance of child’s sensation.

Ans: The educational significance of child’s sensation are mentioned below:

(a) In pre-school stage provision should be made for regular physical checkup of children in regard to their visual and auditory senses.

(b) Teacher should identify such children and offer necessary clinical help to them.

Perception

9. What is Perception?

Ans: Perception is the mental activity of giving meaning to our simple physical experiences of senses. In briefly, meaningful sensation is called perception. It indicates the active state of mind.

10. What are the basic nature and characteristics of Perception?

Ans: The basic nature and characteristics of Perception are mentioned below:

(i) Perception is the mental activity of giving meaning to our simple physical experiences of senses.

(ii) Perception depends upon past learning experiences and in keeping of their memory image or impression in mind.

(iii) Perception is liable to be incorrect and inadequate.

(iv) Perception may not always be objective, but be subjective depending on individual mental make up.

(v) Perception  is influenced by individual aims and objectives, hopes and aspirations in mind.

(vi) Perception depends upon mental maturity attained by the individual.

(vii) Perception is influenced by both subjectivity of individual mind and objectivity of the environmental situation.

(viii) It is a complex type of mental activity that comprises of assimilation, discrimination, association, objectification, and unification process.

11. Write two educational significance of child’s perception in the classroom.

Ans: The two educational significance of child’s perception in the classroom are:

(a) The teacher should co-relate knowledge of the present with the accumulated experiences of the past in his students in course of teaching.

(b) There in lies the validity and usability of giving instances and examples of the past in course of class-room teaching.

12. Mention four differences between Sensation and Perception.

Ans: The four differences between Sensation and Perception are mentioned below:

(i) Sensation is simplest mental state, whereas Perception is complex mental process.

(ii) Sensation is abstract, but Perception is concreate experiences.

(iii) Sensation is inactive or passive, but Perception is active state of mind.

(iv) Sensation gives raw materials, where as Perception is the product of knowledge.

(v) Sensation has no influence of past knowledge and experience, where as Perception grows out to them.

(vi) Sensation is objective, but Perception is objective as well as subjective both.

13. Write two basic relationship between Sensation and Perception.

Ans: The two basic relationship between Sensation and Perception are:

(a) Both sensation and perception are dependents on sensory stimulus.

Important Questions Answer

1. What is Physical basis of Mental life?

Ans: Physical basis of mental life refers to understand the relation between body and mind, concept of nervous system and about knowing process of sensation, perception and conception in this chapter. A good physical health indicates a good mind. Again mental happiness improves our physical health. It makes our digestive, respiratory, and circulatory system of functions. In this regard, Aristotle opinion that ‘education is nothing but creation of a sound mind in the sound mind’.

2. What are the three parts of the human body?

Ans: The three parts of the human body are:

             The neurons are the nerve cells having different size, shape and their complexity. Each one of them is constituted of its cell body and the liquid part at its centre called nucleus. Out of the body of the neuron long fibre like part comes out to be known as axon. At the end part of axon there are a number of roots coming out, called the end brush. Again out of the cell body there are small roots coming out called the dendrites. The dendrites of one cell or neuron come in touch with the other neuron in sending the impulse is called the synapse. It is through this mechanism that the sense experience received by the body organs use to pass on the central nervous system.

7. What is Cells ?

Ans: The life of all living organisms whether it be a plant, animal or human being is made up smallest units in a human body, called Cells.

8.Why the cells are called the smallest unit of life ?

Ans: The life of all living beings is based on the working of the cells. That is why the cells are called the smallest unit of life.

9. What is Cytoplasm ?

Ans: All cells contain a fluid called cytoplasm.

10. What are the three types of Neurons ?

Ans: The three types of neurons are mentioned below:

(a) Sensory neuron:

13. What are the two types of Peripheral Nervous System ?

Ans: The two types of peripheral nervous system are:

(a) Somatic system or Cranial nerves: 

It makes connection of the sense organs and the muscles of the body with the brain. There are of 12 pairs of cranial nerves working for it.

(b) Automatic system or Spinal nerve: 

It is located on both sides of the spinal cord with a total of 31 pairs.

14. What are the two types of Central Nervous System ?

Ans: The two types of Central Nervous System are:

(a) Spinal Cord: 

It lies within the backbone.

(b) Brain: 

It is the centre of all forms of higher mental activities like- thought, intelligence, and emotional reactions.                              

15. What is Spinal Cord ?

Ans: Spinal Cord is the highway of the sensory and motor impulses that run to and from the brain and different parts of the body. There are 31 pairs of spinal nerves that run into the spinal cord.

16. Write two major components of Spinal Cord.

Ans: The two major components of spinal cord are:

(a) Grey matter:

It is located inside of the spinal cord.

(b) White matter:

It is located outside of the spinal cord.

17. Mention four functions of Spinal Cod.

Ans: The four functions of spinal cord are mention below:

(i) Spinal cord connects the brain with different parts of the body.

(ii) It works as a passage covering the sensory and motor impulses.

(iii) It directly controls and regulates the reflex actions like blinking of eye lids, sneezing, coughing and salivation.

(iv) It controls habitual and automatic activities like walking, running and knitting which do not require voluntary attention.

18. What is Brain ?

Ans: Brain is the most important part of the body of the central nervous system which forms higher mental activities like- thoughts, intelligence, and emotional reactions.

19. What are the different parts of the Brain ?

Ans: There are mainly three parts of the brain, namely:

(i) Cerebrum or fore brain.

(ii) Mid-brain.

(iii) Cerebellum or hind brain.

            Other parts of the brain are:

(a) Thalamus.

(b) Medulla oblongata.

(c) Pons variole.

(d) Cerebral cortex.

(e) Spinal cord.

(f) Pituitary gland.

(g) Corpus callosum.

Cerebrum or Fore Brain.

It is the larger part of the brain and is the seat of all forms of higher mental activity. It is divided into two halves called right and left hemisphere. Both right and left hemisphere of this brain are connected by a thick band of fibres which is called the corpus callosum brain. Again the brain of corpus callosum covered by a layer of grey matters with convolutions or twisting folds called cerebral cortex brain. The brain of cerebral cortex brain again subdivided into four loves or areas namely:

(a) Frontal lobe.

(b) Parietal lobe.

(c) Occipital lobe.

(d) Temporal lobe.

Again there are two fissures or narrow opening on the cerebral cortex brain namely:

(a) Fissure of Orlando.

(b) Fissure of Sylvius.       

Functions of Cerebrum or Fore Brain: 

Functions of the cerebrum or fore brain are highly complicated which may be stored out below:

(i) It controls and regulates all parts of the body and their psycho-physical activities.

(ii) It receives information from all the receptor organs and sends messages to them.

(iii) It controls all the voluntary muscular activities and behaviour of individual.

(iv) It acts as the centre of all forms of intellectual activities like- memory, thinking, reasoning and problem solving.

(v) Feeling and emotions experienced in different situations are also originated from this part of the brain.

(vi) Different sensory areas and the lobes function as unitary whole.

Mid-Brain:

This part of the brain is located between the cerebrum and the cerebellum. It is concerned with as a relay centre of nervous impulses and also regulates nature of physical motion of the individual.

Cerebellum or Hind Brain

The cerebellum part or hind of the brain is located behind and beneath of the brain cerebrum or fore brain. Its weight is about 140 grams. This brain is mainly responsible for maintaining equilibrium of the body and steadiness of movement. It controls and co-ordinates muscular movement and also controls finer senses of art, painting, drawing, games and sports, manual dexterity and motor skill etc.

Thalamus

This part of the brain is located at the centre of the brain just below the cerebrum. There are four different parts of it named. These are:

(i) Dorsal thalamus.

(ii) Epi-thalamus.

(iii) Hypo-thalamus.

(iv) Sub-thalamus.

The dorsal thalamus part of the brain passes sensory impulses to the cerebrum which is also known as sensory centre. The other rest of the three parts acts as a motor centre and the hypothalamus part is also controls emotional experience of individual.

Medulla Oblongata

This is the upper part of the spinal cord. It contains the nerve cells and fibre tracts connecting the cerebrum. It is the centre of blood circulation and respiratory function. A person may even die if this part is injured. It controls breathing as well as heart rate. It also acts as a sleep centre.

Pons Variole

This part of the brain is a thick bundle fibres which connects the two halves to the cerebellum with the cerebrum and the medulla oblongata. It forms a bridge in between the vital parts of the brain. Here, right hemisphere of the cerebrum controls the left side and the left hemisphere controls the right side of the body.

20. Mention two basic functions of the Brain.

Ans: The two basic functions of the brain are:

(a) Cognitive functions like- learning, memory, thinking etc.

(b) The regulation of physiology of the body.

21. What are called Receptors Mechanism?

Ans: Our five sense organs that is eye, ear, nose, skin and tongue are constituted of some receptors cells capable of receiving sense impression out of stimuli in environment, So they are called the receptors.

22. What are the two types of receptors mechanism? Give example.

Ans: The two types of receptors mechanism are:

(a) External receptor: For example –  eye, ear, nose, tongue and skin.

(b) Internal receptor: For example – Pain, hunger, etc.

23. What are the different parts of structure of the sense of vision eye?

Ans: There are different parts of structure of the sense of vision eye. So, the major parts of structure are mentioned below:

(a) Cornea:

The thick layer which is exists in front of the eye ball that is called Cornea.

(b) Aqueous humour:

Behind the cornea rests the transparent and liquid substance is called Aqueous humour.

(c) The Iris:

Behind the back of the humour there is exists two black circular parts, one is upper regions and second one is lower regions called iris.

(d) Pupil:

In between upper and lower regions of the two parts of the circular, there may be seen the deep black hole that is called the Pupil.

(e)  The Lens:

Behind the pupil there exists a transparent and solid part that is called the lens.

(f) Ciliary Muscles:

The lens is fixed with the muscular part in all sides which is called the ciliary muscles.

(g) Vitreous Humour:

In ciliary muscles, there is exists a big circular area with jelly-like substance inside the eye ball called vitreous humour. This humour is covered by three layers.

(h) The Retina:

In the inner layer of the vitreous, there are some sensitive cells covering two-third of the area called the retina. Retina of the inner layer is constituted of two types of receptive cells called cons and rods.

(i) Choroid:

The middle layer of the vitreous humour is constituted of black substance called choroid.

(j) Sclerotic Coat:

The outer layer of the vitreous humour is constituted of white substance called sclerotic coat.

(k) Blind Spot:

The part of the retina from where the optic nerve begins is called the blind spot. Here the cons and rods are totally absent.

(l) Yellow Spot:

There is another spot on the retina where the cons and rods are more concentrated to give maximum visual senses is called yellow-spot.

N.B: The most important parts of structure of the sense of vision Eye are namely, 1. Cornea. 2. The iris. 3. The lens and 4. The retina.

24. What are the three major or main parts of structure of the sense of Ear?

Ans: The three major or main parts of the sense of ear are namely:

(a) The Outer Ear:

This part is consisted of its hole in the middle that enters into the interior region which is called Auditory canal. At the end of the canal there is the thin and sensitive membrane called the ear drum. It receives and transmits the sound wave into interior region.

(b) The Middle Ear:

It is consisted of a cave in which there are three small bones namely, hammer or ossicles, anvil or incus and stirrup or steppes bone are arranged in a chain order in this part. The stirrup bone which is touches the oval window at its inner end. Out of the middle ear, there is a tube passes down to the neck which is connected to the nose called eustachian tube.

(c) The Inner Ear:

This part is started with the oval window that connects the three semi-circular canals and the cochlea that acts like a spring. They are transmitting the impulse of sound through auditory nerve to the auditory centre of the brain.

25. What is the third major name of sensory organ?

Ans: Skin.

26. What are major four types of tactual senses of skin?

Ans: The different types of tactual senses of skin are :

(a) Pain.

(b) Pressure and touch.

(c) Warmth.

(d) Cold.

    Along with these, there are some other types of tactual senses which are mentioned below:

(e) Itching.

(f) Burning.

(g) Softness.

(h) Hardness.

(i) Smoothness.

(j) Roughness.

(k) Dryness.

(l) Wetness etc. They indicate the magnitude of physical experiences of this kind being received.

Again, we should know that Physiological structure of the skin may be divided into three layer. These are:

(i) Epidermis Layer:

This type of skin is located on the surface of the body with a very thin membrane, where sensory experiences remain absent.

(ii) Dermis Layer:

It is located under the epidermis which gives different cutaneous senses.

(iii) Fat Layer:

It is located under the dermis as a thick layer of the muscles called fat layer. It gives rise to physical weight of individual.

 Other parts of skin are:

(iv) Oil Gland.

(v) Hair Follicle.

(vi) Blood Vessels.

(v) Sweet Gland.

Point to be remember:
  • Each eye is about 25 mm in diameter and weighs about 7gm.
  • The sense vision of eye is called the queen of receptors.
  • Skin is the third major sensory organ and it gives cutaneous sensation.
  • It serves as the alternative sense organ to seeing.
  • As a specific sense organ, skin cover the whole body organism but it does not give equal sensory stimulation to all the parts.
  • Outer parts of the body, skin sensation is found to be more intense than the inner parts of the organism.

Important Questions Answer

Methods of Educational Psychology

1. What are the different method of Educational Psychology. Briefly explain any two of them.

Educational psychology has its own method of study which are employed to improve teaching learning process in the classroom. The method uses to gather facts about the nature of children to know how they learn, how they develop and how the various aspects of a child’s personality passes through the several stages of growth and development. Educational Psychologist have adopted various means and methods. A few of them are mentioned below:

(a) Introspection Method.

(b) Observation Method.

(c) Clinical Method.

(d) Experimental Method.

(e) Case Study Method.

(f) Sociometric Method.

(g) Project or Projective Method.

(h) Statistical Method.

Introspection Method

2. Briefly explain the concept of Introspection method and its merits and demerits.

Introspection method is that type of method which is examine our own mental process of thoughts, feelings and motives. In this method, one places oneself in the place of the other person and tries to understand his feelings.

            This is the oldest method of educational psychology. Here, The word ‘Introspection’ means self study or inner action of the mind. This method is composed of two words, “Intro” means ‘within’ and “aspection” means ‘looking’. Therefore, the combination word ‘introspection’ means ‘self observation’ or ‘looking within ones own mental stage’.

For example: Suppose you are happy, and in the state of happiness, you look within yourself. Then that means you are introspecting your own mental feelings and examining what is going on in your mental process in the state of happiness.

Merits of Introspection Method:

(a) This is the method which is cheapest and most economical. We do not need any apparatus or laboratory for its use.

(b) This method can be used any time and anywhere.

(c) This method is very simple and is readily available to the individual.

(d) This method helps us in understanding our mental experiences and their improvement.

(e) It is the only method where individual can know his emotions and feelings itself.

Demerits of Introspection Method:

(a) In this method, Study has to be made when the mind is working, which has to be done by the individual himself. Otherwise, it will be disappears due to their emotional state like- anger, sorrow, etc.

(b) This method can be applied only in the case of normal individuals but not for abnormal individuals.

(c) Introspection can not made by children.

(d) In this method, The observer has to be highly trained and skilled person.

(e) It is criticised as a subjective method. That is why, the data acquired through it are may not at all reliable.

Observation Method

3. Write in brief on observation method and its merits and demerits.

Observation means to notice something. It is an important method of educational psychology. This methods includes the observation of the behaviour of a person at different times. The various mental feelings and anger, fear, love, happiness, sadness, etc. can be observed under this method by the outward expression of a person.

          This method tries to study human nature by observing expressed behaviour in various situations. There are different types of observation like- direct and indirect, natural and artificial, planned and unplanned, participant and non participant, etc.

Advantages of Observation method :

(i) With the help of this method, Behavioural problems in children can be located and preventive measures can be adopted.

(ii) This method can be used with children of all ages who are shy and problematic.

(iii) This method can be used in every situation where it does not require any special tool or equipment.

Disadvantages of Observation method:

(i) If the subject comes to know that he is being observed he may not behave naturally.

(ii) If the observer does not record the behaviour during the time of observation, he may forget a part of it when he tries to record it.

(iii) The observer may get only a small sample of students behaviour. It is very difficult to observe everything that a student does.

Clinical Method

4. Write a short note on clinical method, its merits and demerits.

The clinical method is an important method of educational psychology. This method used primarily to study behavioural problems of maladjusted individuals. This method is related to the field of medicine. The main purpose of this method is to study a particular individuals problem as a ‘case’ or ‘cases’ of a group to detect problems and suggested remedial measures.

Advantages or merits of the method of Clinical:

(i) This method takes into account the past and present history of the ‘case’ to study behavioural problems.

(ii) It also studies unconscious behaviour along with overt behaviour.

(iii) This method is regarded as a scientific one and it yields reliable results.

Disadvantages or demerits of the method of Clinical:

(i) It is difficult to observe complex behaviour and to provide useful remedies.

(ii) The interpretation of the case study may not always be correct because of the observers own intuition and theoretical.

Experimental Method

5. Write about experimental method, its merits and demerits.

This method is one of the popular method of studying educational psychology. This method implies the study of the behaviour in a controlled situation that is experimental laboratory. In this method , the cause of the problem is found out before finding the solution, experiment are then caried out. This method can also be applied to test the mental abilities and intelligence of the students through certain tests. But experiment has to be very careful while drawing conclusion.

Advantages or merits of Experiment Method:

(i) This method is based on real experiment and therefore, the findings are reliable.

(ii) It helps a teacher to understand a child better after analysing the data.

(iii) As the conditions are under control the different mental process of the child can be studied accuracy.

Disadvantages or demerits of Experimental Method:

(i) This method is not always possible to control all conditions properly.

(ii) The experiment can be carried out by trained persons only.

(iii) If proper rapport can not be established between the subjects and the experimenter, the result will not be correct.

(iv) As lot of apparatus are required to carry out the experiment so that the method becomes expensive.

Case Study Method

6. Write short note on case study method, its merits and demerits.

Case study method is one of the important method of educational psychology. This method is used in the case of a problem of child. In this method, the history of the family of the child, his early life, student life, home and school life are studied thoroughly. This method is applied on children having psychological problem like- learning difficulties, behavioural problems, emotional disturbance etc. But not only in case of problematic children, this method also used in case of gifted children also.

Advantages or merits of Case Study Method:

(i) Case study method is useful and popular method used for studying special characteristics in individuals.

(ii) It helps to understand the root causes of behavioural problems faced by the subject after analysing the obtained data.

(iii) It also helps teacher to adopt remedial measures and rehabilitation of problems of children.

Disadvantages of Case Study Method:

(i) Case study method is a lengthy and time consuming.

(ii) The Collection of data and their analysis is difficult in this method.

(iii) The finding are always not reliable because it depends upon the information provided by the person himself which may not be authentic.

Socio-Metric Method

7. Who introduced socio-metric method ? Write its merits and demerits.

Socio-metric method is one another method of educational psychology which was first developed in 1946 by Dr. J.L. Moreno and Hellen Jennings. This method studies the social behaviour of individual relationship that exists between individuals or among members of a particular group to provide an interesting study of their nature of social relationship for measuring the status of each individuals. The nature and the degree of such relationship can be objectively assessed by using questionnaire, check list, interview, rating scales, standard tests etc.

Advantages or merits of Socio-metric method:

(i) Socio-metric method helps to make study the social relationship of an individual or among members of the group.

(ii) This method gives us an understanding of the likings and disliking’s of all the members of the groups.

(iii) Through this method teacher may know the most accepted and rejected students to organize group activity of the students in various academic and non- academic field out of it.

Disadvantages or demerits of Socio-metric method:

(i) Socio-metric method can be used to test only one trait of personality that is sociability.

(ii) The process of collection of data is not very scientific as if done through collection of opinion of member of particular group.

(iii) The response of a child regarding some questions may be affected by peer pressure.

Project or Projective Method

8. Write a brief concept of Projective Method. Enumerated its merits and demerits.

Project or projective method is a psycho-analytical method of educational psychology. This method applied in knowing the unconscious and repressed elements of individual mind. This method provides opportunity to evoke responses from unconscious mind which reveal a persons desire, hopes and wishes that could not be fulfilled in the reality. Such responses are drawn by presenting a broad range of testing materials like- pictures, ink-blot cards, drawing and painting, free association test, sentence completion, arranging and interpreting picture situations, filling in the blanks and so on. The responses are expected to reveal one’s inmost thoughts, ideas, emotions and complexes that have been repressed.

Advantages or merits of Projective method:

(i) Projective method is very helpful for psychiatrist for dragonising and treating mental disorders.

(ii) Through this method a complete picture of the personality of a person can be obtained.

(iii) This method also helps to externalize the inner thoughts and ideas of an individual.

Disadvantages or demerits of Projective method:

(i) Project projective method is time consuming and interpretation of the response is very difficult.

(ii) A common classroom teacher can not apply it because for the administration of projective tests special training is necessary.

Statistical Method

9. Write a brief concept of Statistical Method. Mention its merits and demerits.

Statistical method is also a one of the method of educational psychology. This method is being used for study and analysis of human behaviour and responses. In this method, the data is made which is collected by the experimenter on various occasion. This method uses to compare the intellectual development of two children or the same child over the years as he develops. This method also helps to compare the results of two classes, two schools, and so on. Statistical methods used are consisted of measure of central tendency, variability, percentile, coefficient of correlation, etc. Use these methods  can simplify the complex data for objective and numerical observation of the result with greater reliability.

Advantages or merits of Statistical method:

(i) The calculations are accurate hence findings are reliable.

(ii) The facts collected has to be accurate for accuracy of the method.

(iii) One very important merits of this method is that scientific procedures are always followed in every steps of any statistical method.

Disadvantages or demerits of Statistical method:

(i) A common teacher is not capable of applying it as this  method requires specially trained personnel.

(ii) If proper statistical method is not applied, the findings may be wrong and hence harmful for the subject.

Important Questions Answer

1. What do you mean by Education?

Ans: In simple term, Education is nothing but it is a dynamic, continues and life long process of development of an individual which begins at the birth and continues throughout our life for acquiring knowledge and experiences that we acquire at home, school, playground, newspapers, radio, television, movies, etc. It helps to complete development of a man’s personality, as a whole.

           So therefore, we can say that Education is life and life itself is education which can help to modify our behaviour, character and knowledge in all aspects of human development.

2. Give any one definition of Education.

Ans: Different educationist has given different definition of education which are mentioned below:

(i) M.K Gandhi defines, “By education I mean an all round drawing out of the best in the child and man body, mind and spirit.”

(ii) According to Swamy Vivekananda, “Education is the manifestation of divine perfection, already existing in man.”

(iii) Aristotle speaks of education as “the creation of a sound mind in a sound mind.”

(iv) Pestalozzi indicates  education as “the natural, harmonious and progressive development of man’s innate powers.”

(vii) Plato opinions that, “Education is the capacity of feel pleasure and pain at the right moment.”

(viii) Sir Percy Nunn says “Education is the complete development of the individuality of the child so that he can make an original contribution to human life…”

3. Briefly explain Etymological meaning of the term ‘Education’.

Ans: The term ‘Education’ has been derived from four ‘Latin’ words. These are- EDUCO, EDUCARE, EDUCERE and EDUCATUM. 

     Firstly, It comes from two combination words “E” and “DUCO. Here, ‘E’ means “Out of” and “DUCO” means “Lead out”. Thus “EDUCO” means ‘to lead out’ the inner power of man. 

       Secondly, the word “Education” originated from three ‘Latin’ words, namely:

(a) EDUCARE:

It means ‘to bring up’ or ‘to nourish’. Here, education is considered as a process, not a product.

(b) EDUCERE:

It means ‘to lead out’ or ‘to draw out’. Here, Education is considered as ‘the latent potential of the child from within’.

(c) EDUCATUM:

It denotes ‘the act of teaching’ or ‘training’. Here, Education is considered as ‘the principles and practice of teaching’.

Point to be Remember

  • ‘EDUCO’ and ‘EDUCERE’ refers to ‘Education’ as an act of development from within whereas ‘EUCARE’ and ‘EDUCATUM’ implies that ‘Education’ is an act of putting in something from outside sources.

4. Write briefly about the concept of narrow and wider meaning of education.

Ans: In the narrow and in its restricted  sense education means ‘schooling’. Here, Everything is systematic, prefix, and pre-determined. The curriculum, discipline, deliberate efforts by the teachers inculcate certain values, habits or attitudes in children, method of teaching, and examination, marks or grades are followed in the school. A learner can get proper employment after getting a certificate from these institution.

        So, we can say that narrow meaning of education is a systematic process to achieve the definite goals of education through classroom instruction.

       On the other hand, In the wider and unrestricted sense all experiences of our life are said to be education. Here, education is not limited to four walls of the classroom. It comprises totality of our experiences which covers man’s physical, mental, social, emotional, and moral aspects of experiences from birth to death. These knowledge, experience and skills can gained through the house, temple, church, family. Playground, club, society even school which gives true realization of a man’s life. 

    Therefore, we indicate that education is life and life itself  is education which helps us to modify our behaviour, character and knowledge in all aspects of human development which are regarded as the wider meaning of education.

5. Make distinguish between Narrow and Wider meaning of education.

Ans: The distinguish between narrow and wider meaning of education are mentioned below:

(i) Narrow meaning of education is planned and organized process. On the other hand, Wider meaning of education is a social process.

ii. Narrow meaning of education which starts with students entry in school and ends with instruction completion, While wider meaning of education starts from birth and goes throughout life.

iii. Narrow meaning of education education is limited to schooling only, whereas wider meaning of education goes beyond schooling and instruction.

iv. In narrow meaning, the aim of education imparts limited knowledge in specific subjects.  On the contrary, the aim of education focusses on overall development of  students in wider sense.

v. In narrow meaning of education, contents included only academic subjects traditionally taught in the schools, But contents are based on overall learning experiences of students in the field of wider meaning of education.

6. Education is a ‘Bio-polar’ as well as ‘Tri-polar’ process. Explain briefly.

Ans: Sir John Adams in his book entitled “Evolution of Educational Theory” said that education is a bio-polar process which is considered two poles, namely:

(a) Teacher.
(b) Students.

Here, both are equally important in the process of education because If the teacher gives, the child receives and if the teacher instruct, the child follows. Here, the teacher seeks the modification of the development not only through imparting knowledge and skills but also through the direct influences on the child’s personality. So therefore, we can say that there is an interaction between the teacher and the child which is very essential.

          On the other hand, John Dewey considered education is a tri-polar process. He said that educational process not only has a psychological side involving the teacher (educator) and the educand (students), but also has a sociological aspects too. It means the process of education contains three poles, namely:

(a) Teacher.
(b) Student.
(c) Social or educational environment.

   Here, the teacher designs, plan, execute and evaluate students experiences to understand the child’s interest, capacities, aptitudes, and also try to modify the personality of the students. So therefore, we can say that these three factors actively cooperate in the efficient and successful working of the educational process which determines the aims, contents, method of teaching in which the teacher and the child both lives.

7. Write a short note on ‘Education as a life long process’.

Ans: Yes, It is true that education is a continues and life long process which begins at the birth and continues throughout our life. It includes the effects of everything that influences human personality for acquiring knowledge, skills, experiences and competencies through formal, informal and non-formal learning throughout the entire life span.

      So therefore, we can say that education is considered as a life long process pf striving for perfection.

8. Write short note on ‘Education as modification of human behaviour’.

Ans: Yes, It is true that education as modification of human behaviour because of the following reason:

(a) Education is a process which develops our learning factors that bring relatively enduring or permanent changes in our behaviour.

(b) Education can change our behaviour that covers the whole life of a man to modify itself through the process of modification.

(c) It represent a progressive change in behaviour by the acquisition of new behaviour which gives to meet our desire, needs and requirements for change.

           So therefore, above reason we can say that education is considered as modification of human behaviour.

9. Write short note on ‘Education as an instrument of social change.

Ans: Yes, It is true that education as an instrument of social change because of the following reason:

(a) Education helps us in increasing the mental ability of a persons thinking, pattern of social relationship, attitudes, and lifestyle of a person.

(b) It helps to bring such instant changes like- concept of right and wrong, what should be done or what not.

(c) It also helps to modified our old customs, faiths and belief to bring about progressive changes in them.

iii. Man is a social animal by instinct. Therefore, this aim can helps to moulds and makes him a perfect human being.

iv. It also helps to make a close relationship between the school and the outside world.

Demerits of Social aim education:

i. It is against the development of individuality of the individual.

ii. Society ignores the legitimate needs, desires and interests of the individual.

iii. It reduces individual to a mere non-entity.

iv. It makes individual only as a tool of government.

28. The individual and social aim of education are not contradictory but complementary to each other. Discuss this statement.

Ans: Yes, although there are differences between individual and social aim of education but both are interdependent or complementary to each other because of the following different points of view which are mentioned below:

i. Individual and social aim of education both focus on the development of the society as a whole.

ii. The development of man depends on the development of society.

iii. The individual can not realize himself. Every human being is social by nature and he is capable of reaching his fullest development only in the society.

iv. John Dewey emphasized that ”the development of society is of prime importance for the development of individuality.”

v. Sir Percy Nunn believed that the individuals could develop their goodness in the need of a social environment.

vi. Again, Progressive thinkers feel that when individuals are developed society will automatically be developed.

        So therefore, we can say that individual can not survive without society and society also can not survive without individual. Both individual and social aim of education are interdependent and complementary to each other.

29. What is Vocational aim of Education? What makes this aim so important for the society?

Ans: In simple term, Vocational aim of Education means the education which is imparted the necessary education and training to their own children in the vocation to prepares people to work individual to be self-employed with requisite sill to move in their careers is called vocational aim of education.

          This aims are very important for the society which are mentioned in the following below:

i. Vocational aim makes one economically self sufficient.

ii. It can make individuals good, loyal and productive citizens.

iii. It may help to utilise individual capacity for social progress.

iv. It can serve the present reality of life and needs of individual.

v. It can solve the socio-economic problems including the problem of unemployment in the youths.

vi. It helps the state in making effective use of man power resources for country’s development.

30. Write two disadvantages of Vocational aim of education.

Ans: The two disadvantages of Vocational aim of education are mentioned below:

i. This aims fails to satisfy the mental and spiritual need of high order.

ii. It could not satisfy the cultural and aesthetic need of man.

31. Write short note on “Liberal aim of education.”

Ans: Liberal aim of education is that which is indicate the education entailed in the classical tradition of education. For example- art, music, literature and philosophy. This aim is also known as ‘Cultural aim of education.’

           This liberal aim of education helps students to develop a sense of social responsibility as well as strong and transferable intellectual and practical knowledge and skills in real world setting.

         This aim can serves the aesthetic, moral and spiritual need of man. It may also can help man to utilise his leisure hour in a more healthy and creative way.

32. What should be the aim of education in a democracy?

Ans: As we know that education is the great instrument of social emancipation by which democracy establishes, maintains and protects the spirit of equality among its members.

       Therefore, the aim of education in a democracy must be formulated on the basis of the following ways:

i. Creation of democratic personality or Development of personality:

For self expression and for the full development of human personality, education should develop literacy, artistic and cultural interests of the students. For this purpose subjects like- art, craft, music, dancing, etc. should be included in the scheme of studies.

ii. Education for leadership:

In order to make democracy function successful, it is essential to inculcate the qualities of leadership in our youth. Education should train the youth to provide leadership in the social, political, industrial and cultural fields.

iii. Developing national and international outlook:

The purpose of this aim of education is to make the citizens practise the values of democracy, love for our nation and have feeling of universal brotherhood and international understanding.

iv. Equalization of educational opportunity:

The true democratic education demands that education should be the birthright of every individual. So, equal educational opportunities should be provided to all members of the society.

v. Improvement of Vocational Efficiency:

In order to achieve this aim, education should be much greater emphasis on crafts and productive work introduced diversification of courses at the secondary stage like-agriculture, technical, commercial or other practical courses.

33. Make distinguish between Individual and social aim of Education.

Ans: The distinguish or difference between Individual and social aim of education are mentioned below:

i. Individual aim of education is based on philosophy of naturalism . On the other hand, Social aim of education is based on philosophy of pragmatism.

ii. Individual aim which gives importance on biological heredity of man, While social aim of education gives importance on social heredity of man.

iii. The aim of individual education is to development of man’s biological potential, Where as, the social aim of education is to attainment of social efficiency of man.

Chapter-1

Philosophy and Education

1. What is Philosophy?

Ans: Philosophy is the study or creation of theories which seeks to understand the mysteries of existence and reality. It tries to discourse the nature of the truth and knowledge and to find what is of basic value and importance in life. It also examines the relationship between humanity and nature and between individual and society. Thus, we can say that philosophy is a form of inquiry – a process of analysis, criticism, interpretation, and speculation.

2. Write about the meaning of the term of ‘Philosophy’.

Ans: The term ‘Philosophy’ comes from a combination of two Greek words – ‘’philos” meaning ’love of’ and “sophi” meaning ‘wisdom’. Etymologically, philosophy means ‘love of wisdom’.

3. Give one definition of Philosophy.

Ans: Different philosopher has given different definition of philosophy. Some of philosopher’s definition are mentioned below:

(i) According to Aristotle, “Philosophy is the science which investigate the nature of being, as it is in itself.”

(ii) According to Cicero and Marcus Tullius, “Philosophy is the mother of all arts and the true medicine of mind.”

(iii) According to Dr. Rahdakrishnan, ”Philosophy is a logical enquiry into the nature of reality.”

4. State the basic characteristics of Philosophy.

Ans: The four basic characteristics of Philosophy are mentioned below:

i. Philosophy is a search for truth and reality.

ii. Philosophy is the art of thinking rationally and systematically of the reality as a whole of the universe.

iii. Philosophy is study of general principles and understanding of all that comes in the range of human experience.

iv. Philosophy is the study of metaphysics beyond one physical and its relation with the physical world.

5. Briefly explain about the branches of Philosophy.

Ans: The branches of philosophy are most commonly taken to be logic, ethics, metaphysics, epistemology, and aesthetic. Here is a brief sketch of each:

1. Logic:

Logic is the method of reasoning and argumentation which is concerned with providing sound methods for distinguishing good from bad reasoning. It enquiries into various kinds of proof or evidence and the condition of their validity and also investigates the nature and validity of various kinds of inference, deduction and induction.

        The term ’logic’ is derived from the Greek word ‘logos’ which has a variety of meaning like- thought, idea, argument, account, reason, or principle.

   The are basically two kinds of logic. These are namely:

(a) Deductive logic:

It is concerned with determining when an argument is valid. For example: conclusive inference.

(b) Inductive logic:

It is concerned with the correctness of inferences for which the evidence is not conclusive. For example: probable inference. 

2. Ethics:

Ethics is also often called ‘moral philosophy’ which take up the meaning of our moral concepts such as- right action, obligation, and justice and formulates principles to guide moral decisions, whether in private or public life.

        The word “ethics” is derived from the Greek word ‘’ethos’’ which means ‘custom or character’.

        There are three areas of ethical theories:

(a) Meta ethics:

It deals with the nature of moral judgement.

(b) Normative ethics:

It is concerned with the content of moral judgements and the criteria for what is right or wrong.

(c) Applied ethics:

It studies to looks at controversial topics like war, animal rights and capital punishment.

        Ethics also has the following major sub-fields:

  • Political philosophy.
  • Social philosophy.
  • Philosophy of law.
  • Medical ethics.
  • Business ethics.
3. Epistemology:

Epistemology is that branch of philosophy which deals with the nature, origin or sources, types, structure, scope, methods, and validity of knowledge. It encompasses the nature of concepts, the constructing of the concepts, the validity of the senses, logical reasoning, as well as thoughts ideas, memories, emotions, and all mental things. It also analyses the nature of knowledge and how it relates to similar notions such as truth, belief, and justification.

4. Metaphysics:

Metaphysics is a branch of philosophy which is concerned with the nature of reality, of what exists in the world such as- substance, identity, the nature of mind, and freewill. It encompasses everything that exists, as well as the nature of existence itself.

       Traditionally, the word “Metaphysics” comes from ‘Greece’ in a two combination words ‘meta’ meaning ‘over’ and physics meaning ‘beyond’. Thus, the combination means over and beyond physics. 

                   There are two kinds of metaphysic. These are:

(a) General metaphysics (universal):

It studies the ultimate reality like- categories, universals, attributes etc.

(b) Special metaphysics:

It studies seriously one particular subject like- philosophy of mind and psychology, personal identity, ad aesthetics.

          Again, Aristotle originally split his metaphysics into three main sections which are mentioned below:

i. Ontology:

It studies of being and existence, including the definition and classification of entities, physical or mental, the nature of properties and the nature of change.

ii. Natural Theology:

It studies of God, including the nature of religion and the world, existence of the divine, questions about the creation, and the various other religions or spiritual issues.

iii. Universal science:

It studies first principles of logic and reasoning such as the law of non-contradiction.

5. Aesthetics:

Aesthetics branch of philosophy deals with the nature of art, including the performing arts and painting, sculpture, and literature. The word “aesthetics” is derived from the Greek word ‘aisthetikos’ meaning ‘of sense perception’.

6. Explain the relationship between Science and Philosophy.

Ans: Yes, both science and philosophy are interrelated and interconnected which has endured for thousands of years particularly in the work of Galileo, Descartes, Kepler, Newton, Einstein among others. So, some point of the relation between science and philosophy can be stated in the following below:

i. Both science and philosophy are engaged in the search of truth.

ii. Philosophy examines scientific method.

iii. Philosophy guides future courses of scientific process.

iv. At the same time, scientific research influences philosophical progress.

v. Philosophy integrates science and examines scientific assumption.

vi. Philosophy provides a constructive criticism of sciences.

      So, to conclude we can say that both science and philosophy grew out of the reflective thinking and are promoted by an impartial love of truth.

7. Make differentiate between science and philosophy.

Ans: The major difference between philosophy and science can be stated below:

i. Philosophy is best linked to the human heart. On the other hand, Science is to the human mind.

ii. Philosophy uses questioning and a series of analyses through logical arguments and dialectics. Where as, Science is more concerned with empirical evidence and testable hypotheses.

iii. Science bases its explanation from experimentation and observation. But, Philosophy bases its explanation on argument of principles.

iv. Philosophy and science both are engaged in different activities and differ from in their method, scope, problem, conclusion etc.

7. Discuss the relationship between Philosophy and Education.

Ans: Yes, it is true that both philosophy and education are closely interrelated which are enumerated in the following below:

i. Education and philosophy are dynamic because both are deal with human being and their life.

iii. Philosophy sets the goal and create a good life for the individual whereas education finds out the solution by which the goal of a human being can be fulfilled.

iii. Philosophy determines the goal of life which is consciously adopted by education.

iv. Philosophy determines the various aspects of education.

v. Philosophy represents a system of thought whereas education embraces that thought in the content of instruction.

vi. Philosophy is wisdom and education transmit that wisdom from one generation to the other.

vii. Philosophy embodies a way of life whereas education prepares a life of an individual.

viii. James Ross said, “Education is the dynamic sides of philosophy.”

ix. John Adams rightly said, “Education is the dynamic side of philosophy. It is the active aspect of philosophical belief.”

x. John Dewey said, “Philosophy is the theory of education in its most general phases.”

xi. Percy Nunn view, “Education aims are correlative to ideals of life.”

xii. Spencer’s view, “True education is practicable to true philosophers.”

xiii. Fichte’s view, “The art of education will never attain complete clearness without philosophy.”

xiv. Gentile view, “Education without philosophy would mean a failure to understand the precise nature of education.”

         So therefore, we can say that both education and philosophy are closely related and both are called the sides of the same coin.

9. What do you mean by Educational Philosophy?

Ans: Educational philosophy is nothing but it is the practical application of philosophical principles in the educational field which direct the various aspects of education towards the aim of human life. It is also a branch of general philosophy which comprises of the principles, ideals, and theories of life of particular people, at a particular time, in a particular society or country and it puts them in to practice in the field of education. In short, we can say that educational philosophy relates philosophy of life through the medium of education.

10. Explain the functions of Educational Philosophy.

Ans: The functions of educational philosophy are generally associated with aims of education, the programme of education, examination and evaluation of educational organization, methods, contents, measurement and so on to identify and explain the true nature of man, as the principle of object of education which are briefly discussed under the below:

i. Determining the aspects of education:

Educational philosophy determines various aspects of education which are briefly explain here in the following ways:

(a) Aim of Education:

Different educational philosophers have suggested vast and varied aims and objectives of educational process. These includes physical, mental, social, emotional, spiritual, moral, ethical, cultural, academic, lingual, and pragmatic for the development of human personality.

(b) Curriculum:

With the help of educational philosophy, Curriculum designer can construct curriculum according to the need, interest, and ability of the child.

(c) Method of teaching:

With the help of educational philosophy, we can able to choose suitable methods of teaching according to the nature of the subject and school environment to make classroom teaching more effective and attractive.

(d) Discipline:

Knowledge of educational philosophy determine the nature of form to follow a desirable discipline.

(e) Teacher and students:

Educational philosophy determines the role and quality of teacher as well as student in the school and relationship with each other in a diversified society.

(f) Administration:

Knowledge of education philosophy also determines to established in democratic or totalitarian system of administration in the field of educational institutions.

ii. Harmonizing old and new traditions in the field of education:

This function emphasise that old traditions are replaced by the new traditions. But this process of replacement is not always smooth because of certain orthodox in the society. So therefore, there is a need of coordinating in order to maintain harmony between both and this function can be performed with the help of study of education philosophy.

iii. Providing the educational planners, administrators, and educators to achieve educational development:

This function of educational philosophy indicates that a true philosopher can give a practical shape of education which guides to the educational planners, administrators, and educators with the right vision to attain the educational goals efficiently.

iv. Preparing the young generation to face the challenges of the modern time:

As we know that our present society is not static. It changes the value, tradition, custom, culture etc from time to time. So that educational philosophy helps

to understand the relationship between the goals and complexities of society to develop critical attitude towards the individual’s life in diverse society to face challenges of the modern time.

     On the other hand, According to Brubacher, there are mainly three functions of educational philosophy which are briefly explain below:

(a) Speculative function:

Speculative function of educational philosophy leads the educator and the administrator from common sense approach to rational and perspective approach. It also helps to guides the teacher by giving him an overall view of the whole thing in terms of facts, data, information, etc. to make assessment of everything.

(b) Normative function:

Normative function of educational philosophy refers to set of norms, goals, principles, standards etc. If we applying these norms, then it is possible to decide a right decision. But in the absence of these norms, the teacher or the administrator or the controlling authorities fail to make the right decision.

(c) Critical function:

Critical function of educational philosophy examines the contents, methodology in the sphere of education and refines to it make fully suitable.

1. What is Statistics?

Ans: Statistics is a process of scientific method that deals with description of data in the form of numerical value which helps for collection, tabulation, classification, analysis and interpretation of data related to predetermined purpose is called Statistics.

2. Explain the meaning of the term ‘Statistics’.

Ans: The term ‘Statistics’ have been derived from ‘Latin’ word ‘Status’, Greek word ‘Statistique’, Italian word ‘Statista’, and German word ‘Statistic’. So that meaning of these word is ‘Political state’ or ‘a government’.

3. Discuss the needs and importance of statistics in education and psychology.

Ans: Statistics is very important in education and psychology which are discussed in the following bellows:

i. For Construction of Psycholigical Test:

Statistical methods helps in the construction of various psychological test like- achievement test, intelligence test, aptitude test, interest inventories, attitudes etc.

ii. For presentation score:

It helps us in proper and systematic presentation of the scores obtained from various educational and psychological tests and measure.

iii. To make prediction:

It helps the teacher to render guidance to the students to make prediction regarding their future progress.

iv. To know individual difference:

Statistics also helps to know individual difference of the students in terms of their academic performance.

v. To keep various types of Record:

It provides the teachers to keep various records of his students as well as of the school record.

vi. To make selection, classification and promotion:

Statistics also helps the teachers to make selection, classification and promotion of the students.

4. What are the different methods of Statistics?

Ans: There are some methods of statistics to study and evaluate data collected from various sources:

(a) Frequency distribution.

(b) Measures of central tendency.

(c) Measures of variability.

(d) Graphical representation.

5. What do you mean by Frequency distribution? What steps you will follow do construct a frequency distribution table?

Ans: The scores of data which are tabulated in a frequency table is known as frequency distribution or frequency distribution table. For constructing a frequency distribution table the following steps are essentials:

i. Determination of Range:

Firstly, We should find out the range of raw scores. Range refers to the difference between the highest and the lowest scores.

ii. Class-Interval:

After finding the range, Secondly we should determined the class-interval. The class-interval depends upon the range and the number of interval required according to the range of the scores.

iii. Midpoint of the class-interval:

The midpoint of interval is the logical choice that the scores are represented with in a given class-interval by some single value.

iv. Tallies:

After determining the class-interval, we should make tallies. A tally represent a scores that lies in anyone particular class-interval.

v. Frequencies:

After making the tallies, In final steps, we should given the number of frequencies. The total number of frequencies is the same as the total number of scores. We represent by ‘N’ the total number of frequencies.       

N.B- Without mid point of the class-interval, frequency distribution table we can put. But giving mid point of the class-interval is better for other purpose.

6. Tabulate the following 50 scores into frequency distribution using an interval of 5.

75, 62, 37, 48, 63, 62, 87, 62, 65, 81
71, 67, 46, 61, 38, 55, 68, 52, 55, 62
41, 60, 58, 83, 48, 57, 65, 60, 74, 51
51, 61, 77, 70, 77, 78, 32, 63, 35, 63
56, 73, 71, 69, 60, 74, 46, 68, 43, 64.

Solution:

Highest Score= 87

Lowest score= 32

Range= 87-32=55

                                               N= 50

7. What is Measures of central tendency? Write two uses of measures of central tendency.

Ans: Measure of Central Tendency is the central value of a set of data which is defined as “the statistical measure that identifies a single as representative of an entire distribution.”

      The two uses of measure of central tendency are mention below:

(a) It is an average which represents all of the scores made by the group as a whole.

(b) It enables to compare two or more groups in terms of typical performance.

8. What are the types of measures of central tendency?

Ans: There are commonly three types of measures of central tendency. These are:

(a) Arithmetic Mean.

(b) Median

(c) Mode

9. What is Mean or Arithmetic Mean? Write three uses or merits of Mean as a measure of central tendency.

Ans: The scores are added and their sum is then divided by the number of the item is called Mean. It is defined as ‘the average of a set of number which reflects the central tendency of the position of the numbers.’

           The two uses of Mean as a measure of central tendency are:

(a) The mean can be used to know average idea or picture of a set of data.

(b) It is used to comparing two or more groups or frequency distribution in terms of typical or characteristics performance.

(c) It is used because it is the simplest but most useful measure of central tendency.

10. What is Median?

Ans: The median is the value in the middle of a data set that lie 50% of the case when the data are arranged in ascending or descending order which is called Median.

11. Mention three advantages or merits of Median as a measure of central tendency.

Ans: The three advantages or merits of Median as a measure of central tendency are mentioned below:

(a) Median is very easy to calculate and also simple to understand as a measure of central tendency.

(b) It is not affected by the extreme values between the largest and the smallest values because it is a positional average which is not dependent on magnitude.

(c) It’s value can be represented graphically with the help of ogive curves. But it is not possible in case of an arithmetic mean.

12. Write two disadvantages or demerits of Median as a measure of central tendency.

Ans: The two disadvantages or demerits of Median as a measure of central tendency.

(a) In ungrouped data, the arranging scores of the data in ascending or descending order of magnitude is time consuming in case of a large number of observations.

(b) It is a positional average which does not consider the magnitude of all the items.

13. What is Mode ?

Ans: The number of scores that occurs in the list several times which is known as Mode.

The formula of Mode is –

Mode= 3 Median – 2 Mean

14. Write two uses of Mode.

Ans: The two uses of mode are mentioned below:

(i) Mode is used where quick and appropriately measure of central tendency is desired.

(ii) Mode is used when we need to know the most often recurring score or value of the item in a series.

(iii) We complete mode when we have a graphical representation of the distribution.

15. What do you mean by Measure of Variability?

Ans: The extended data which cases tend to gather round the central tendency and to which they disperse themselves in a data set or statistical distribution is called Measures of Variability or Variation.

16. What are the different methods of Measures of Variability?

Ans: There are mainly four methods of measures of variability which are mentioned below:

(i) Range

(ii) Quartile Deviation

(iii) Mean Deviation or Average deviation

(iv) Standard Deviation

17. What is Range?

Ans: The difference between the highest and the lowest scores in a series is called Range.

18. Write two uses of Range.

Ans: The two uses of Range are:

(a) When rough and quick comparison is needed then we can use range as a measure of variability.

(b) When knowledge of extreme scores is all that is wanted then we can use range as a measure of variability.

19. Write the formula of Range in ungrouped data.

Ans: (Highest score – lowest score).

20. Write two difference between polygon and histogram.

Ans: The two difference between polygon and histogram are:

(i) The frequency polygon is a line graph of the given frequency distribution whereas, Histogram is essentially the bar graph of this distribution.

(ii) In the frequency polygon, all of the scores within given interval are represented by the midpoint of the interval. But in a histogram the scores are spread uniformly over the entire interval.

(iii) Frequency polygon gives a much better conception to know the trend of the distribution, But a Histogram is unable to tell such a thing.
