COVAR
Returns covariance, the average of the products of deviations for each data point pair. Use covariance to determine the relationship between two data sets. For example, you can examine whether greater income accompanies greater levels of education.
Syntax
COVAR(array1,array2)
Array1 is the first cell range of integers.
Array2 is the second cell range of integers.
Remarks
- The arguments must be either numbers or names, arrays, or references that contain numbers.
- If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
- If array1 and array2 have different numbers of data points, COVAR returns the #N/A error value.
- If either array1 or array2 is empty, COVAR returns the #DIV/0! error value.
- The covariance is:
Example
COVAR({3,2,4,5,6}, {9,7,12,15,17})
equals 5.2
