STDDEV(numeric_exp)

Returns the Standard Deviation of the Population of numeric_exp, where numeric_exp is a sampling of a larger population.

Description

The standard deviation statistical function is used to depict dispersion among the measures of a given population.

To find the standard deviation of a population, the variance must first be defined, since the square root of the variance equals the standard deviation of the population.

To calculate the standard deviation of a sample of a population, you must first calculate the variance of the sample.
