Question

If the absolute dispersion is the
standard deviation s and if the average
is the mean X, then the relative
dispersion is called the
A) coefficient of variation
B) coefficient of Standarad Deviation
C) coefficient of Mean Deviation
D) coefficient of Median​

Answer 1

Given:

             The standard deviation is S

             The average mean is X

To find:

              The relative dispersion =?

Step-by-step explanation:

Let the standard deviation is ' S ' & the average mean is ' X '.

A statical measure of the dispersion of data points around the mean is called the coefficient of variation.

It is also defined as the percentage ratio of the stansard deviation to the average mean.

Mathematically it is expressed as,

Coefficient of variance = $\displaystyle \frac{standard deviation}{Average mean} * 100$

                               CV =  $\displaystyle \frac{S}{X} * 100$
