How to Calculate the Coefficient of Variation
Formula
CV = (Standard Deviation / Mean
The CV is a dimensionless measure of relative variability. It allows comparison of spread across datasets with different units or vastly different means. A CV of 10% means the standard deviation is 10% of the mean.
Example Calculation
A dataset has a mean of 50 and standard deviation of 5. Find the CV.
- 01CV = (5 / |50|) * 100%
- 02CV = 0.10 * 100%
- 03CV = 10%
