VAR

Calculates the sample variance of the values in a data set.

Syntax:

VAR(list)

Returns the sample variance of the values in the list.

list may be an array, a range of cells, or a comma-separated list of values.

Formula:

VAR = (ni=n (xi2) − (i=n xi)2) ÷ (n⋅(n − 1))

where n is the number of values and xi is the i-th value.

Example:

VAR(A1:A15)

returns the variance of the contents of cells in the range A1:A15.
