Coefficient of va

Answer :

Given: Coefficient of variation of two distributions are 60% and 80% respectively, and their standard deviations are 21 and 16 respectively.


Need to find: Arithmetic means of the distributions.


For the first distribution,


Coefficient of variation (CV) is 60%, and the standard deviation (SD) is 21.


We know that,






For the first distribution,


Coefficient of variation (CV) is 80%, and the standard deviation (SD) is 16.


We know that,






Therefore, the arithmetic mean of 1st distribution is 35 and the arithmetic mean of 2nd distribution is 20.
