Bonferroni Correction

Control the family-wise probability of any false rejection across m tests by comparing each p-value with alpha/m, or equivalently multiplying each p-value by m, without requiring independence.

Core Idea

Bonferroni correction controls the probability of one or more false rejections across a fixed family of \(m\) hypothesis tests by testing each hypothesis at \(\alpha/m\), or equivalently by multiplying each raw p-value by \(m\) and truncating at one. Its guarantee does not require test independence.

The canonical identity is narrower than the phrase’s everyday use. The procedure requires a declared test family, a family-wise error budget, a finite count \(m\), and a uniform division of that budget across family members. Its conservatism is the price of a simple, dependence-robust union-bound guarantee.

What It Is Not

It is one procedure within Multiple Comparisons Correction, not an alias for that family. False Discovery Rate is a criterion about the proportion of false discoveries; Benjamini–Hochberg is a different procedure targeting that criterion. Look-Elsewhere problems can require an effective rather than literal count of opportunities.

Scope of Application

The recipe runs unchanged in genomics, physics, medicine, and online experiments, but each use imports the same statistical-testing apparatus. Its reach is broad application of a statistical method, not substrate removal.

A shared label or downstream consequence is insufficient; the load-bearing roles must survive.

Clarity

Bonferroni Correction separates a specific relation from neighboring ideas that can produce similar observations. It is one procedure within Multiple Comparisons Correction, not an alias for that family. False Discovery Rate is a criterion about the proportion of false discoveries; Benjamini–Hochberg is a different procedure targeting that criterion. Look-Elsewhere problems can require an effective rather than literal count of opportunities.

Manages Complexity

The abstraction compresses recurring cases into one inspectable model. An analyst can track the structural roles, compare mechanisms, and locate exactly which missing commitment invalidates an analogy.

Abstract Reasoning

Identify the candidate roles, test the defining relation, then challenge the nearest boundary case. Dividing alpha by the number of observations rather than the number of tested claims is not Bonferroni correction.

Knowledge Transfer

The recipe runs unchanged in genomics, physics, medicine, and online experiments, but each use imports the same statistical-testing apparatus. Its reach is broad application of a statistical method, not substrate removal. Transfer is warranted only when the same causal, formal, or relational work survives.

Examples

Qualifying pattern. Bonferroni correction controls the probability of one or more false rejections across a fixed family of \(m\) hypothesis tests by testing each hypothesis at \(\alpha/m\), or equivalently by multiplying each raw p-value by \(m\) and truncating at one. Its guarantee does not require test independence.

Boundary case. Dividing alpha by the number of observations rather than the number of tested claims is not Bonferroni correction.

Structural Tensions

T1 — Reach versus identity inflation. Broad use is valuable only while every defining role survives.

T2 — Observation versus mechanism. Similar outcomes can arise from neighboring mechanisms, so classification follows the relation and its counterfactual rather than appearance.

Structural Core vs. Domain Accent

The recipe runs unchanged in genomics, physics, medicine, and online experiments, but each use imports the same statistical-testing apparatus. Its reach is broad application of a statistical method, not substrate removal. The transferable residue is thinner than the named mechanism, whose domain vocabulary and causal apparatus remain constitutive.
