Dougal in his book ‘An outline of psychology’ stated that “Interest is latent attention and attention is interest in action.” He said that long attention remains hidden in our mind, that state may be called interest. The same latent or hidden interest when becomes active, it is called attention. Thus according to Mc. Dougal attention and interest are very closely associated.

          Again J.S Ross in his book ‘Groundwork of Educational Psychology ’ stated attention and interest are like ‘two sides of the same coin.’ As interest creates attention and also attention when put voluntary can develop interest.

         On the other hand, educational point of view attention and interest are regarded as both ‘means and ends’ in education because academic achievement of students primarily depends upon these two factors. Which motivates once to learn something. Hence it may be called ‘means; in education.

           Again modern educationists are of the opinion that a teacher primarily duty is to develop attention and interest in students and interest in students for self learning so that may called ‘ends’ in education.

           So therefore, from the point of view of different psychologist and educationalists we can say that both attention and interest are both related each other and also can say that both are the two sides of the same coin.

Next forth stage, we should make tallies. A tally represent a scores that lies in anyone particular class-interval.

(v) Frequencies:

At the final stage, we should make the tallies and 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.
