Answer a few questions and get a clear recommendation for which statistical test fits your data. Built for researchers, students, and anyone analysing data. Choose the correct statistical test for your data. WhichStats guides you to the right test so you can analyse your data with confidence. Answer simple questions about your study design, variables, and goals, and get a tailored recommendation—with assumptions, what to report, and what to do if assumptions fail. Guided wizard Step through a short decision tree: describe your outcome (continuous, binary, count, etc.), number of groups, whether data are paired or independent, and your goal (compare groups, predict, survival, agreement, and more). The app recommends a test and explains why it fits. Clear, practical recommendations Each recommendation includes: • The suggested test • Key assumptions to check • What to report (e.g. effect sizes, CIs) • Suggested plots • What to do if assumptions are violated Explore tests Browse and filter tests by goal and variable type. Tap any test for a summary of typical use, assumptions, reporting tips, and suggested plots. Glossary Look up terms (e.g. normal distribution, p-value, confidence interval, logistic regression, survival analysis) with short definitions and real-world examples from lab and clinical research. Pro Unlock the full report (what to report, suggested plots, alternatives), decision path, and extra guidance on effect size, post-hoc tests, and multiple testing. Free tier still gives you the recommended test name and assumptions. Whether you’re running a t-test, ANOVA, regression, or survival analysis, WhichStats helps you choose and report the right test.
