Function name:
COVAR
Category:
Statistical Analysis
Summary:
Returns the covariance of the product of paired deviations.
Syntax:
COVAR(Data1; Data2)
Returns:
Returns a real number which is the covariance (the average of the products of deviations) for each data point pair in two data sets, Data1 and Data2.
Arguments:
Data1 is a reference to a range of cells that is considered the first data set.
Data2 is a reference to a range of cells that is considered the second data set.
- If a cell contains text, or empty cells, then the function ignores these values.
- If Data1 and Data2 have different numbers of data points then the function returns an error value.
- If the standard deviation of Data1 and Data2 is 0 then the function returns an error value.
- If any of the arguments is empty, or if the standard deviation of their values equals zero, COVAR returns an error value.
Additional details:
- The formula for COVAR is:
where x̄ and ӯ are mean values.
- COVAR and COVARIANCE.P perform the same function.
- For more details on covariance, visit Wikipedia.
