Returns the Variance of the population of numeric_exp, where numeric_exp is a sampling of a larger population.

Description

The variance is used to depict the dispersion among the measures of a given population. To find the variance, you must first find the mean of the scores, find the measurement by which each score differs from the mean, find the square root of the difference, then divide the number by (n-1).

In a list of 'n' numbers, the Variance is the sum of the square of the differences between each number and the mean of the sample of the population.

 

Parameters

numeric_exp must be a number, or a numeric expression.
