The statistical test chooser for survey and small-sample research
Which statistical test should I use? Four short questions, then a recommendation with assumptions, runnable R code, JASP steps, and an APA reporting sentence. Companion to the surveyframe R package.
It depends on your goal, your design, and your data. StatChooser asks four short questions (goal, design, data, measurement) and recommends a specific test, such as an independent samples t test, a chi-square test, a one-way ANOVA, a Pearson or Spearman correlation, a regression, a mediation or moderation analysis, reliability, EFA or CFA, or SEM, along with its assumptions and runnable R code.
StatChooser is a free, open-source statistical test chooser for survey and small-sample research. It is the companion front end to the surveyframe R package: every recommendation carries a method ID that runs directly in surveyframe's run_analysis_plan(), and each result includes a small-sample note and a ready-to-adopt survey questionnaire.
Yes. StatChooser is free and open source under the MIT licence, with no ads and no paid tiers.
