You can see in the matrix that anytime there is a correlation between the same variable, the correlation coefficient value is 1. The correlation coefficient is a value that ranges from +1 to -1.Ī value of 0 means there is no linear correlation between the two variables.Ī value of +1 means there is a perfectly positive linear correlation between the two variables so, as one variable increases, so does the other. So, in my example, the correlation coefficient value for the relationship between Variable 1 and Variable 4 is 0.108. The numbers in the table represent Pearson correlation coefficient values. The top row and first column will list each of the variables entered into the test. To create the correlation matrix, go to Data> Data Analysis.įrom the list, select the Correlation option and click OK. Use the Data Analysis ToolkPak to create the correlation matrix in Excel Now we are ready to create the correlation matrix. Now, when you click on the Data ribbon at the top, you should see a Data Analysis button in a sub-section called Analyze. Then, ensure you tick the Analysis ToolPak add-in, and click OK.

To install this add-on, go to File> Options.Īt the bottom, you want to manage the Excel Add-ins, and click the Go button. This is an add-on created by Microsoft to provide data analysis tools for statistical analyses. Perhaps the easiest way to create a correlation matrix in Excel is to use the Data Analysis ToolPak.

What I want to do is to create a correlation matrix, which contains the Pearson correlation coefficient values between each of my 10 different variables. How to create a correlation matrix in Excel
