How to Use CORREL Formula in Excel
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.
The CORREL function syntax has the following arguments:
- Array1 Required. A cell range of values.
- Array2 Required. A second cell range of values.
- 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:
are the sample means AVERAGE(array1) and AVERAGE(array2).
Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.
