Intervention Analysis Tool
This tool, called the Intervention Analysis Tool (IAT), allows users to compare intervention periods to non-intervention periods by analyzing data from a CSV or Excel file. Users can choose from three different designs (AB, ABA, ABAB), and the tool generates a summary table, effect size table, and two plots (color and black and white) to visualize the data. The IAT can be useful for researchers, educators, or other professionals who want to evaluate the effectiveness of interventions in a variety of settings.
Click the "Choose a spreadsheet file" button and select the file you want to analyze.
Select the appropriate columns from the dropdown menu and select the single-case study design used to collect the data. Then click Analyze Data.
The tool will automatically generate a summary table, effect size comparison table, and both color and black/white visualizations.
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 IAT or interpret its results, please review the technical directions page. You can also use this sample file to practice.
