How it works

1Enter or paste the requested sample values, summary inputs or contingency data.
2Choose the method, confidence level or test options when available, then run the calculation.
3Review the estimate/test statistic together with p-value, confidence interval, effect size and method notes where available.

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 Spearman p-value exact?

No. Significance is based on the usual t approximation applied to the rank correlation. Exact small-sample/permutation inference may differ.
