What this tool is for
Coefficient of Variation Calculator supports math checking in math calculators by showing how apply the formula shown on this page to the entered values. The page keeps the inputs, formula, and example together so the calculation can be checked before the number is reused.
When to use it
Use it when standard deviation and mean are already known and you need a quick estimate before comparing options, checking a worksheet, or copying the result into another workflow.
Inputs
- Standard deviation is one of the direct inputs used to calculate coefficient of variation.
- Mean is one of the direct inputs used to calculate coefficient of variation.
Formula
CV = (stddev / mean) x 100
Example
Stddev 12 and mean 50 gives CV of 24%.
What the result means
The result labeled "Coefficient of variation" is the direct output of CV = (stddev / mean) x 100. In the worked example, stddev 12 and mean 50 gives CV of 24%.
