Statistical significance

A measure of whether a selection-rate gap is large enough, given the sample size, to be unlikely to occur by chance. Courts have used a two-to-three standard-deviation benchmark (Castaneda v. Partida, 1977; Hazelwood School District v. United States, 1977). It complements the four-fifths rule: a small gap in a large pool can be significant, and a large ratio in a tiny pool may not be.

Defined in 2 GAGE programs, which carry 2 distinct definitions of it. The wording above is taught in AI Governance: Applied Mastery.
