Multiple testing correction calculator

Calculate bonferroni adjusted p values and holm adjusted p values with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use bonferroni adjusted p values and holm adjusted p values to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Bonferroni adjusted p values

Bonferroni=min(1,m p); Holm cumulative maxima ascending; BH reverse cumulative minima.

Holm adjusted p values

Bonferroni=min(1,m p); Holm cumulative maxima ascending; BH reverse cumulative minima.

Benjamini–Hochberg adjusted p values

Bonferroni=min(1,m p); Holm cumulative maxima ascending; BH reverse cumulative minima.

Bonferroni rejected hypothesis indices

Bonferroni=min(1,m p); Holm cumulative maxima ascending; BH reverse cumulative minima.

Holm rejected hypothesis indices

Bonferroni=min(1,m p); Holm cumulative maxima ascending; BH reverse cumulative minima.

BH rejected hypothesis indices

Bonferroni=min(1,m p); Holm cumulative maxima ascending; BH reverse cumulative minima.

Assumptions & limits

Assumptions & limits

  • Calculation uses the entered values and stated mathematical model; quantities must use the labelled units. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Bonferroni=min(1,m p); Holm cumulative maxima ascending; BH reverse cumulative minima.
