Correlation Matrix


A correlation matrix is a quick and easy way to identify the strength of relationships between two variables, such as the relationship between a demographic group and a student outcome. This correlation matrix generator is an incredibly easy and efficient way for teachers to gain better insight into their data. With just a few clicks, the generator will prepare a color-coded visualization that you can use to jump-start your data conversations.



  1. Prepare your data. Your data must consist of columns with headings for each variable you want to examine. Save your data as a .CSV file.

  2. Upload your data to the generator by selecting “Browse” and selecting your file from the list. Remember, you should never upload personally identifiable data for yourself or your students to the web!

  3. The generator will automatically produce a correlation matrix for the data in your spreadsheet. 

  4. The graphic from this page can be copied and pasted into a document or slide show to share with your data team.
