COVAR (Array1,Array2)
where,
- is the first array of integers or reference to the cells containing array
- is the second array of integers or reference to the cells containing array
- COVAR(), returns covariance, the average of the products of paired deviations.
Description
COVAR (Array1,Array2)
- COVAR is used to determine the relationship between two data sets.
- Arguments , can be numbers or can be names, arrays or references containing numbers.
- Values containing text, logical values or empty cells are ignored.
- If either or is empty, Calci displays a NaN error message.
- The number of data points in and should be same, else Calci displays a #N/A error message.
ZOS
- The syntax is to use the COVAR function in ZOS is
- and are the set of values to find the Covariance.
- For e.g.,COVAR([10,20,15,17,19],[12,22,31,16,45])
- COVAR([50..57],[17..24])
Examples
Array 1 | Array 2 | |
2 | 21 | |
4 | 22 | |
6 | 23 | |
8 | 24 | |
10 | 25 |
=COVAR(A2:A6,B2:B6) : Returns 4 as the output. =COVAR(A2:A5,[12,13,14,15]) : Returns 2.5 as the output.
