Description
COVAR returns the covariance of two data sets.
Strings and empty cells are simply ignored.
This function is Excel compatible.
Examples
Let us assume that the cells A1, A2, ..., A5 contain numbers 11.4, 17.3, 21.3, 25.9, and 40.1, and the cells B1, B2, ... B5 23.2, 25.8, 29.9, 33.5, and 42.7. Then
COVAR(A1:A5,B1:B5) equals 65.858.
