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.
In a statistic class, 10 scores were randomly selected with the following results were obtained: 74, 73, 87, 57, 71, 68, 65, 77, 67, 66. What are the inner fences? What is the coefficient of variation?

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