This article will show you how to calculate the correlation coefficient in . Excel.

Calculate the correlation coefficient

The correlation coefficient (values ​​from -1 to +1) tells you how related two variables are to each other

A correlation coefficient of +1 indicates a completely positive correlation. As variable X increases, variable Y increases. When variable X decreases, variable Y decreases.

A correlation coefficient of -1 indicates a completely negative correlation. As variable X increases, variable Z decreases. When variable X decreases, variable Z increases.

A correlation coefficient close to 0 indicates no correlation.

1. On the Data tab click Data Analysis.

2. Select Correlation and click OK.

3. For example, select the range A1:C6 as Input Range.

4. Check Labels in the first row.

5. Select cell A8 as Output Range.

6. Press OK

Result

Conclusion: variables A and C have a positive correlation (0.91). The variables A and B are not correlated (0,19). Variables B and C are also uncorrelated (0.11).
