Terms of use

Educational Use

Statoma explains common statistical procedures such as t-tests, p-values, confidence intervals, sample size planning, and chi-square tests. These tools can support learning, checking calculations, and preparing clearer interpretations. They do not determine whether a study was designed well, whether a model is appropriate for every dataset, or whether a result should guide a medical, legal, financial, regulatory, or safety decision.

Users remain responsible for choosing methods that match their data, assumptions, study design, and reporting context. A calculator can make arithmetic more transparent, but it cannot verify the quality of sampling, measurement, randomization, coding, independence, missing-data handling, or domain-specific interpretation.

Accuracy And Limitations

Statoma aims to provide careful formulas, tested calculation functions, and plain-English explanations. Still, no educational website can guarantee that every result is correct for every use case. Statistical methods often have conditions that are easy to overlook, and many real analyses require decisions that go beyond a summary-statistic calculator.

Before relying on a result, check the inputs, units, tails, hypotheses, degrees of freedom, confidence level, expected counts, and any assumptions named on the calculator page. For coursework, follow the requirements of the class. For research, follow the analysis plan and reporting standards in the field. For applied decisions, consult an appropriately qualified professional.

Acceptable Use

Use Statoma in a way that respects the site, other users, and the limits of the tools. Do not attempt to interfere with the site, bypass security controls, overload hosting infrastructure, scrape in a disruptive way, or present Statoma results as a professional certification of an analysis. Do not enter confidential personal data when aggregate statistics would answer the question.

You may link to Statoma pages, cite them as learning resources, and use calculator output as part of your own work, provided you remain responsible for the interpretation and context. The Statoma calculator index is the best entry point when sharing the tool set.

Changes To These Terms

These terms should evolve with the product. If Statoma adds accounts, uploads, saved work, paid features, embedded content, or other capabilities, the terms should be reviewed and updated before those features are published. Questions about corrections or terms can be routed through the Statoma contact page.
