Variance is tabulated in units squared. Standard deviation, being the square root of that quantity, therefore measures the spread of data about the mean, measured in the same units as the data. Said more formally, the standard deviation is the root mean square (RMS) deviation of values from their arithmetic mean.

Mean Variance Standard Deviation Ex post variance calculation: The average return is subtracted from each single period return; this difference is then squared. The squared differences are summed. This sum is divided by the number of periods (using population data) or the number of periods minus 1 (using sample data). Year Rt
