Statistics Calculator FAQ
Which test should I use?
Two groups of independent values: unpaired t test (or Mann–Whitney if not normal). The same subjects measured twice: paired t test (or Wilcoxon). Three or more groups: one-way ANOVA (or Kruskal–Wallis). Counts in categories: chi-square or Fisher’s exact test.
Is it accurate?
The calculations are checked against widely used open-source scientific libraries and published reference data.
Can I enter mean, SD and n instead of raw data?
Yes: set the Column table format to “Mean, SD, N” or “Mean, SEM, N”. Descriptive statistics, unpaired t tests and ANOVA work from summaries; nonparametric tests need the raw values.
Is my data uploaded?
No. Everything is calculated in your browser.
