Calculating the Standard Deviation. If x is a number, then the difference "x - mean" is called its deviation. In a data set, there are as many deviations as there are items in the data set. The deviations are used to calculate the standard deviation. If the numbers belong to a population, in symbols a deviation is x − μ .

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.
