How this tool works
The approach depends on three things: how your data were collected (your design), what one row of your data represents, and what kind of outcome you measured. The tool matches those answers to methods commonly used for that combination, then adjusts for sample size. It uses fixed rules written by a measurement and statistics specialist, so the same answers always give the same result. No AI is involved, and nothing you enter leaves your browser.
