Terms of use

These terms govern use of WhichStat for Excel (the Microsoft Excel add-in and whichstat.com), a product of NCU Technology.

WhichStat is a free educational / analytical laboratory for descriptive statistics. Ranked summaries are the best supported among candidates on the selected sample. They are not a claim that a statistic is the true value for a population, and they are not a substitute for a statistician, instructor sign-off, or licensed professional advice.

There is no paid plan and no payment processor for this product.

You remain responsible for how results are used in coursework, quality work, or publication. Hypothesis tests are not included in the current product.

Sister products: WhichDist for Excel and WhichForecast for Excel. WhichStat does not fit distributions and does not forecast.
