Abstract
In numerous applications of the analysis of variance it is necessary to compute the power of F tests having numerically high alpha (significance) levels. This article tabulates the power of F tests for numerator degrees of freedom, df = 1, 2, 3, 6, 9, 12; denominator df = 3, 6, 9, 12, 15, 20, 40, 60, 120; alternative hypotheses, phi = 2.(.2)3.0; and significance levels, alpha = .05, .10(.10),.50. The use of these tables is illustrated with a brief numerical example.Keywords
