The Excel COVARIANCE.P function calculates the population covariance of two supplied sets of values.
The function is new in Excel 2010 and so is not available in earlier versions of Excel. However, the Covariance.P function is simply an updated version of the Covar function that is available in earlier versions of Excel.
Where array1 and array2 are two arrays of numeric values, that are of equal length.
Note that the Covariance.P function ignores text values and logical values that are supplied to the function as part of an array.
Columns A and B of the above spreadsheet on the right contain two sets of values.
The population covariance of the values in columns A and B of the spreadsheet can be calculated using the Excel Covariance.P function, as follows:
This gives the result 16.633125, which indicates a positive correlation between the two sets of values.
For further information and examples of the Excel Covariance.P function, see the Microsoft Office website.
If you get an error from the Excel Covariance.P Function, this is likely to be one of the following:
|#N/A||-||Occurs if the two supplied arrays have different lengths.|
|#VALUE!||-||Occurs if one or both of the supplied arrays are empty.|
