Syntax of CORREL function
CORREL(array1, array2)
The CORREL function syntax has the following arguments:
- Array1 Required. A cell range of values.

CORREL formula explanation
- 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 a different number of data points, CORREL returns the #N/A error value.
- If either Array1 or Array2 is empty, or if s (the standard deviation) of their values equals zero, CORREL returns the #DIV/0! error value.
