## 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.

**First, determine the standard deviation.**Calculate the standard deviation of the data set.

**Next, determine the mean.**Calculate the mean or average of the data set.

**Finally, calculate the coefficient of variation.**Using the formula above, calculate the coefficient of variation.
