Question

Standard deviation of a data is 21.2,mean
is 36.6
then find its C.V.​

Answer 1

$coefficient \: of \: variation \: (c.v) = \frac{standard \: deviation}{mean} \\ c.v = \frac{21.2}{36.6} \times 100\% \\ c.v = \frac{2120}{36.6} \: \% \\ c.v = 57.923467 \: \% \\ c.v = 57.9 \: \%$ Therefore, Coefficient of variation ( C. V ) = 57.9 %
