Coefficient of Variation Calculator

Your details

Raw data gives you a full breakdown. Summary mode is for when you only have mean and SD. Reverse-solve finds the SD required to achieve a target CV.
Use sample when your data is a subset of a larger group.
Multiplies the CV by (1 + 1/(4n)) to correct for the positive bias in small samples. Only applies when mode is Raw or Summary.
Separate values with commas, spaces, or new lines.
Leave blank to skip. Enter a second dataset to compare its CV against Dataset A.

The standard deviation is 18.01% of the mean.

  • CV is unitless, so you can compare it across data sets measured in different units (dollars vs. kilograms, for example).
  • A lower CV means the values cluster tightly around the mean; a higher CV means they are more spread out relative to their average.

Next stepEnter a second dataset in the Dataset B field to compare relative variability across different scales.
