The formula to calculate the coefficient of standard deviation is:
Coefficient of variation = ( standard deviation / mean ) x 100
or
CV = ( SD/X(bar)) x 100
here, if you want to find the percentage then only multiply by 100 else you can skip this because this is an optional step.
calculating the coefficient of standard deviation is a useful statistic for comparing the degree of variation from one data series to another.
