Data Disaggregation Tool
The Data Disaggregation Tool (DDT) is designed to allow teachers to easily and quickly analyze their student data. With just a few clicks, the DDT will automatically the data from a spreadsheet, disaggregate it by your selected student variable, calculate six descriptive statistics, and create a boxplot to allow you to quickly and easily compare performance between groups of students
Click the "Choose a spreadsheet file" button and select the file you want to analyze.
Once the file is uploaded, two dropdown menus will appear. Select a demographic variable in the first menu and an outcome variable in the second menu.
The tool will automatically generate summary statistics and create a boxplot for the selected columns.
Remember not to upload personally identifiable information when using this tool. If you are uncertain whether your data is appropriate for analysis with this tool, please consult with a member of your organization.
If you need additional help or want more detailed information about how to use the DDT or interpret its results, please review the technical directions page. You can also use this sample file to practice.
