The method, explained

CV = sample standard deviation/mean × 100%.

A WORKED EXAMPLE

Using numbers = 2, 4, 6, 8, the result is 51.6397779 %. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

Use ratio-scale quantities; unstable when the mean is near zero. A descriptive or probability calculation under the stated assumptions. Check the sample design and model before interpreting results.
