SPSS takes hours to learn. R takes months. AI makes up the numbers.

StatEze just gives you the right answer, and lets you verify every single one.

No statistician needed. No AI guesswork. No coding.

The standard analyses your study needs, done right

StatEze covers the everyday statistics of clinical research and runs each one correctly: the right test for your data, the assumptions checked, every number computed and reproducible. What your study needs is here, and it holds up.

The right analysis, chosen correctly

Every number computed, never generated

From your data to a manuscript you can defend

Don't trust us. Recompute us.

Same data, same tests, same numbers. Every test family StatEze runs is checked against an independent reference value, produced outside StatEze's own code, before it ships. And you do not have to take our word for it: we publish worked examples on real, widely cited clinical datasets, each with the chart, the result StatEze computed, and the data. Download any of them, run it in SPSS, and reproduce every value yourself.

Common questions

Does AI calculate my statistics?
No. Every test statistic, p-value, effect size, and confidence interval is computed by SciPy and statsmodels, the same established libraries behind published research, through a fixed, transparent decision tree. No language model is involved in any calculation. That is why your results reproduce exactly and hold up in review.
What do I actually get?
A complete analysis of your dataset: the statistical tests, publication-quality figures, and Methods and Results paragraphs written in journal style. The output is built to be pasted into a manuscript, not exported and reworked.
Is it really free?
Yes. StatEze is in open access and every feature is currently free, with no credit card required.
How do I know the statistics are correct?
Every statistical method is checked against reference results computed independently of StatEze's own code before release. We also publish worked examples on real, widely cited clinical datasets from the published research literature, each with the chart, the result, and the data, so you can download any of them and reproduce every number yourself. Run your own analysis twice and you will get identical numbers each time. Read the validation summary.
Which analyses does StatEze run?
The everyday tests of clinical research: two-group and multi-group comparisons, paired analyses, correlations, regression, and categorical comparisons, in parametric and nonparametric forms. StatEze checks the assumptions and selects an appropriate test for your data.
What does StatEze not handle?
StatEze handles the everyday analyses of clinical and epidemiological research: group comparisons, correlations, regression, and categorical tests, in parametric and nonparametric forms. It is not designed for survival analysis, longitudinal mixed models, complex survey designs, or Bayesian methods. For those, a biostatistician remains the right choice. StatEze is built for the routine analyses researchers currently run in SPSS or send to a statistician for standard processing.
Do I need to install anything?
No. StatEze runs in your browser. Create a free account, upload a dataset, and your first written results arrive in minutes.
