VAR

Calculates the sample variance[1] of the values in a data set.

Syntax:

VAR( list )

Returns the sample variance of the values in the list.

list may be a range of cells, an array, or a comma-separated list of values (which may contain cell references and also ranges of cells as one or more of its elements).

Formula:

VAR, = ( ni 1n (xi2) − (i 1n 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.
