The standard deviation is a measure of how much the numbers deviate from the mean. It is calculated using the formula:

If your data sets are different sizes, it is hard to compare their spread using standard deviation or variance. Therefore we use the coefficient of variation, which is a ratio of the standard deviation to the mean, expressed as a percent.
