Research Tool

Statistical Test Selector

Answer a few questions about your design and get a recommended statistical test, an APA-style reporting template, the test's key assumptions, an effect-size benchmark, and a non-parametric alternative. The recommendation is a deterministic teaching aid — it runs entirely on this page and nothing is stored. It does not replace a methodologist's judgement.

Your design

Answer the questions relevant to your goal; leave the rest on “—”.

1. What is your research question about?

2. Measurement level of your outcome variable

For an association, this is the level of both variables.

3. (Differences) How many groups or conditions?

4. (Differences) Are the groups independent or paired?

5. (Prediction) How many predictors?
