Demerits: 1) It is not easy to understand and easy to calculate 2) As it consider the sum of the squares of deviations of items from the mean. The items away from mean gets more weight age than those near the mean. Thus, standard deviation gives more weight age to extreme value. 18.6 CHECK YOUR PROGRESS 1) What do you mean by Range? 2) What is Mean Deviation? 3) Explain Quartile deviation. 1) Borwankar P.V. – Research Methodology Seth Publisher 1995. 18.8 QUESTION 1) What is standard deviation? What are it merits and demerits? 2) What is mean deviation? Discuss its as merits and demerits.
