When the coefficient hits the clinic: Effect size and the size of the effect

Journal/Book: Behav Brain Sci. 1998; 21: 40 West 20TH Street, New York, NY 10011-4211. Cambridge Univ Press. 211.

Abstract: The usefulness of effect-size differs in utilitarian experiments from its use in theory corroborations. Chow introduces the question of the relationship of effect-size to practical validity and the role of the assessment of ''importance'' in this. This review develops this question and suggests the actuarial table as a replacement for effect-size in practical decision-making.
