ABOUT THIS ANALYSIS

One-way ANOVA calculator with Tukey comparisons

Run one-way ANOVA and Tukey or Tukey–Kramer comparisons in your browser. Inspect confidence intervals, diagnostics and editable scientific figures.

When to use it

One continuous outcome, one factor and independent experimental units.

What to enter

Paste or import observations for 2–20 groups, with at least two included values per group. Keep biological units distinct from technical repeats.

What you get

Group summaries, the ANOVA table, effect sizes, all-pairs Tukey comparisons, residual diagnostics and configurable SVG or high-resolution PNG figures.

Assumptions and limits

Ordinary ANOVA assumes independent errors, appropriate normality and equal population variances. This tool does not support repeated-measures, factorial or nested ANOVA.

Calculations run locally; participant data stays in browser memory. Download your results or project before leaving. This is beta software, with independent statistical review pending.
