Sum

The standard deviation and mean of a data are 6.5 and 12.5 respectively. Find the coefficient of variation.

#### Solution

Standard deviation of a data (σ) = 6.5

Mean of the data (barx) = 12.5

Coefficient of variation = sigma/barx xx 100 %

= 6.5/12.5 xx 100 %

= 52%

Coefficient of variation = 52%

Concept: Coefficient of Variation
