COVARIANCE.P function: Description, Usage, Syntax, Examples and Explanation

What is COVARIANCE.P function in Excel?

COVARIANCE.P function is one of Statistical functions in Microsoft Excel that returns population covariance, the average of the products of deviations for each data point pair in two data sets. Use covariance to determine the relationship between two data sets. For example, you can examine whether greater income accompanies greater levels of education.

Syntax of COVARIANCE.P function

COVARIANCE.P(array1,array2)

The COVARIANCE.P function syntax has the following arguments:

  • Array1     Required. The first cell range of integers.
  • Array2     Required. The second cell range of integers.

COVARIANCE.P formula explanation
