Question
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%
