Question

Mean and standard deviation of runs scored by a cricket player are $80$ and $4$ respectively. Find the coefficient of variation.

Answer 1

Given that:

Standard deviation $\sigma =4$ and Mean $\mu =80$

To find:

Coefficient of variation $c_v=?$

Solution:

Coefficient of variation $c_v=\frac{\sigma }{\mu }=\frac{4}{80}=\frac{1}{20}=0.05$
