Find the mean and standard deviation for your data. Once you calculate those two values, you can use the following formula to find the coefficient of variation:

CV = (sd/mean) * 100
...where sd = standard deviation and * means to multiply.

I hope this will help.

Note: CV is the standard deviation expressed as a percentage of the mean.
