COVAR

Returns the covariance of two sets of data.

Syntax:

COVAR(x;y)

where x and y are ranges or arrays containing the two sets of data.

COVAR calculates:

${\frac {1}{n}}\sum _{i}{(x_{i}-{\bar {x}})(y_{i}-{\bar {y}})}$

where ${\bar {x}}$ and ${\bar {y}}$ are the averages of the ranges x and y.

Advanced topic:

The function COVAR(x;y) is automatically evaluated as array formula.

Example:

COVAR(A1:A30;B1:B30)

returns the covariance of the two sets of data in A1:A30 and B1:B30.
