Next we will discuss a concept which will enable us to compare the relative
variability between two or more different variables. These variables do not
have to necessarily represent the same measurements. This concept relates
the mean and the standard deviation and is called the coefficient of variation.

The Coefficient of Variation
The coefficient of variation (CV) allows us to compare the variation between
two (or more) different variables. Usually, the result is expressed as a
percentage.
