WebThere are manuscripts that simulate power needed for mediation models. Given how these models are computed, G*Power can not calculate power. Check out Fritz & MacKinnon, Psychological Science, 2007, “Required Sample Size to Detect the Mediated Effect.” Do not use g*power for mediation. WebG*Power is a tool to compute statistical power analyses for many different t tests, F tests, χ2 tests, z tests and some exact tests. G*Power can also be used to compute effect … WebApr 29, 2011 · F tests - Linear multiple regression: Fixed model, R² deviation from zero Analysis: A priori: Compute required sample size Input: Effect size f² = 0.15 α err prob = 0.05 Power (1-β err prob) = 0.80 Number of predictors = 3 Output: Noncentrality parameter λ = 11.5500000 Critical F = 2.7300187 Numerator df = 3 Denominator df = 73 Total … head sentence law
