Statistics Workbench
Client-side t-tests, ANOVA, regression, and non-parametric tests.
Last updated July 2026
The Statistics Workbench is a client-side statistics engine. Paste or upload your data and run the analysis entirely in your browser: your raw data never leaves your machine to compute a result, and the engine is covered by its own unit-test suite. It is available on every plan.
Available Tests
Run descriptive statistics and a library of inferential tests, each reporting the statistic, degrees of freedom, p-value, effect size, and confidence intervals where applicable:
- t-tests: one-sample, paired, and two-sample.
- Non-parametric: Mann–Whitney U, Wilcoxon signed-rank, and Kruskal–Wallis.
- ANOVA: one-way analysis of variance.
- Correlation & regression: Pearson and Spearman correlation, and simple linear regression.
- Categorical: the chi-square test of independence.
Exporting Results
Export your results to CSV for downstream reporting, or send them straight into your Research Notebook as a record tied to the analysis.
Optional AI Interpretation
You can optionally ask Olto AI to interpret a result and explain it in plain language. The AI never computes the numbers; every statistic is produced by the deterministic engine. The interpretation step (stats_interpret) is a metered AI call (Researcher and above).
