Table 1 Probabilities for four possible outcomes in a statistical significance test of a research hypothesis.

From: The new accounting for expected adjusted effect test (AEAE test) has higher positive predictive value than a zero-order significance test

An outcome; P = 1
H1 true; P = prior H1 false; P = 1-prior
True positive; P = prior × power False negative; P = prior × (1−power) False positive; P = (1−prior) × α True negative; P = (1−prior) × (1−α)
  1. P: probability; H1: research hypothesis; α: risk for type 1-error
