In this video I'll quickly show you how to find the coefficient of variation. There are two formulas for samples and populations, but these are basically the same and involve dividing the standard deviation by the mean and lastly converting to a percent. The coefficient of variation is useful for comparing the variation of two groups that have different means, or are measured on different scales.
