This article describes the formula syntax and usage of the CORREL function in Microsoft Excel.

## Description

Returns the correlation coefficient of the Array1 and Array2 cell ranges. Use the correlation coefficient to determine the relationship between two properties. For example, you can examine the relationship between a location’s average temperature and the use of air conditioners.

## Syntax

CORREL(array1, array2)

The CORREL function syntax has the following arguments:

• Array1    Required. A cell range of values.
• Array2    Required. A second cell range of values.

## Remarks

• 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.
• The equation for the correlation coefficient is: where are the sample means AVERAGE(array1) and AVERAGE(array2).
