Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Dear student The answer should be Bfor sure at a glance. As I searched there are only 4 ways to calculate relative measure of dispersion so according to it answer should have been 'B' but as relative measure of dispersion are measure of variance so the answer can be 'C' also.
absolute measure of dispersion are range, quartile deviation, mean deviation, standard deviation , and variance. relative measure of dispersion are coefficient of ( range, quartile deviation,mean deviation,standard deviation & variation ).
how can relative measure of dispersion be VARIANCE??
Dear Naresh Kumar a range is also a basic measure of variation
