VARP

Returns the population variance of the values in a data set.

VARP(list)

Calculates the population variance of the values in the list, which may be an array, a range of cells, or a comma-separated list of values.

The equation used is:

(n·Σi=n (xi2) − (Σi=n xi)2) ÷ n2

where xi is each value and n is the number of values.

Example:

VARP(A1:A15)

returns the population variance of those cells in the range A1 to A15.
