Frequently asked questions

Does this statistics calculation upload my data?

No. Entered values are processed locally in your browser with JavaScript.

Should I interpret statistical significance by itself?

No. Review effect size, confidence intervals, study design, assumptions, sampling and multiplicity together with the p-value.

Is the p-value exact?

The reported p-value is a continuity-corrected normal approximation. Exact small-sample inference may differ, especially with ties or many zero differences.
