The Coefficient of Variation is given by:
(A) $$\dfrac{Mean}{\ Standard \ \ deviation } \times 100$$
(B) $$\dfrac{\ Standard \ \ deviation }{Mean}$$
(C) $$\dfrac{Standard \ \ deviation }{Mean }\times 100$$
(D) $$\dfrac{Mean}{Standard \ Deviation}$$

Thecoefficient of variation(CV) is astandardizedmeasure ofdispersion
. It is defined as the ratio of the standard deviationto the mean.
$$CV\quad =\quad \cfrac { \sigma }{ Mean }\times100$$
