CORREL
Syntax:
CORREL ( array-1 , array-2 )
Description: Computes the correlation coefficient of the two cell ranges designated by array-1 and array-2.
Mathematical Formula:
The equation for the correlation coefficient is:
where x and y are the sample means AVERAGE(array-1) and AVERAGE(array-2).
Arguments:
Name |
Type |
Description |
|---|---|---|
array-1 |
array, reference |
The first cell range. If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value 0 are included. |
array-2 |
array, reference |
The second cell range. If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value 0 are included. |
Return Type and Value: number – The correlation coefficient of the cells in two cell ranges.
However, if
array-1 and array-2 have a different number of data points, the return value is unspecified.
array-1 and array-2 is empty, the return value is unspecified.
The standard deviation of the values in array-1 or array-2 equals zero, the return value is unspecified.
