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
The coefficient of variation is vary 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.
