How it works
CV = SD ÷ mean × 100
The coefficient of variation expresses spread relative to the mean, so you can compare variability between datasets of different scales.

Frequently asked questions
Why use CV instead of SD?
CV is unitless, so it compares variability across datasets with different means or units.
What is a high CV?
It depends on the field, but a higher CV means more relative spread around the mean.
