Distribution Analysis Tool

Teachers collect volumes of data every day but learning from that data can be difficult and time consuming. I designed the Distribution Analysis Tool (DAT) to be an incredibly easy and efficient way for teachers to gain better insight into their student data. With just a few clicks, the DAT will prepare a report 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. The DAT can only analyze numerical variables. Save your data as a .CSV file.

  2. Upload your data to the DAT 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 DAT will automatically produce a summary of the first column of your spreadsheet. Use the drop-down box to select other variables to analyze.

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


If you need additional help or want more detailed information about how to use the DAT or interpret its results, please review the technical directions page. You can also use this sample file to practice.
