Returns the population covariance of two series evaluated over a set, using the biased population formula.


Covariance(«Set», «Numeric Expression»[, «Numeric Expression»])


This function evaluates «Set» against the first «Numeric Expression» to get the values for the y-axis. «Set» is evaluated against the second «Numeric Expression», if present, to get the set of values for the x-axis. If the second «Numeric Expression» is not present, the members of «Set» are used as values for the x-axis.

Covariance uses the biased population formula. CovarianceN uses the unbiased population formula.

Note  Empty cells or cells containing text or logical values are ignored; however, cells with values of zero are included.
