# How to use CORREL function

The CORREL function in Excel is used to calculate the correlation coefficient between two data sets. This coefficient is a measure of how closely two sets of data are related.

Here are the steps to use the CORREL function in Excel:

1. First, select a cell where you want to display the result of the correlation coefficient.
2. Type "=" followed by the word "CORREL" in the selected cell.
3. Inside the parentheses, specify the range of cells containing the first set of data, followed by a comma, and then the range of cells containing the second set of data.
4. Press Enter, and the result will be displayed in the selected cell.

For example, if your data sets are in cells A1:A10 and B1:B10, you would use the following formula:

=CORREL(A1:A10, B1:B10)

Excel will then calculate the correlation coefficient between these two sets of data and display the result in the selected cell. The correlation coefficient value will range from -1 to 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation.
