Question

The standard deviation and mean of a data set are $6.5$ and $12.5$ respectively. Then the coefficient of variation is

• A. $52$
• B. $53$
• C. $48$
• D. $49$

Answer 1

The correct option is A $52$

$S.D.\sigma =6.5$
Mean $\overline{x}=12.5$
Coefficient of variation $C.V.=\frac{\sigma }{\overline{x}}\times 100$
$=\frac{6.5}{12.5}\times 100=52$
