Enter the mean and the standard deviation of a population or sample into the calculator to determine the coefficient of variation.

Coefficient of Variation Formula

The following equation can be used to calculate the coefficient of variation of a data set, usually a population or sample.

C = (σ / μ) * 100%

  • Where C is the coefficient of variation (%)
  • σ is the standard deviation
  • μ is the mean or average

Coefficient of Variation

The coefficient of variation is very similar to the standard deviation. In short, it’s a measure of how much a data set varies across a population. It’s different in that it’s then normalized to the population mean which means the coefficient could be applied to a different mean to yield a new standard deviation.

How to calculate coefficient of variation ?

How to calculate coefficient of variation.

  1. First, determine the standard deviation.

    Calculate the standard deviation of the data set.

  2. Next, determine the mean.

    Calculate the mean or average of the data set.

  3. Finally, calculate the coefficient of variation.

    Using the formula above, calculate the coefficient of variation.


What is a coefficient of variation?

A coefficient of variation is coefficient used as a measure of the variation across a data set or population of data.
