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