Free Tool
Psychology Statistical Test Advisor
Use this tool to shortlist the most likely statistical test for a common psychology analysis. It is designed to point you in the right direction, not pretend that four dropdowns can settle every design decision known to humanity.
Describe your analysis
Answer a few questions about what you are trying to do. The output gives a likely best fit, a sensible alternative, and the checks still worth making.
Your shortlist
The tool gives a likely best fit and a nearby alternative. It is there to narrow things down, not to replace actual judgement.
Premium makes more sense when you want more nuanced decision support, assumption guidance, and help with trickier designs rather than straightforward cases.
What Premium does better
- Free: shortlist likely tests for common designs
- Premium: more nuanced support for assumptions, alternatives, and messier designs
- Premium: better when the answer is not obvious and the design is more awkward than the tidy textbook version
