False discovery rate (FDR) is a statistical control method that limits the expected proportion of false positives among all rejected hypotheses in multiple testing. Its parameters are: the target FDR level (q), the set of simultaneous tests, the test statistics, and the correction procedure (e.g. Benjamini-Hochberg). It persists through statistical textbooks, software implementations (R, Python, SAS), and standard practice in genomics, neuroscience, and data science.

Definition
Why it is in scope
A human-made statistical control method for managing the expected proportion of incorrect rejections among all rejections in multiple hypothesis testing. It is a decision-theoretic construct developed to address the problem of false positives when conducting many simultaneous tests, operationalized through the q-value andBH procedure.

False discovery rate is a specific kind of statistical method — a procedure for controlling the expected proportion of incorrect rejections in multiple hypothesis testing. A competent speaker would call it a statistical method. Specific→general per Law 9, nearest kind is statistical method.
- cmsdfit1403uo3vv38tclhy28DERIVED_FROM →
False discovery rate (FDR) was developed from the broader theory of multiple testing correction — multiple testing correction existed first and fed into the specific FDR methodology.

The formal statistical concept of false discovery rate requires p-values to operate — FDR procedures (Benjamini-Hochberg, etc.) compute from p-values. Remove p-values from the statistical toolkit and FDR procedures cease to function. Removal test: without p-values, FDR as a formal measure stops operating.
