WebCohen (1988) hesitantly defined effect sizes as "small, d = .2," "medium, d = .5," and "large, d = .8", stating that "there is a certain risk in inherent in offering conventional operational definitions for those terms for use in power analysis in as diverse a field of inquiry as behavioral science" (p. 25). Effect sizes can also be thought of as the average percentile … WebIn meta-analysis, we can choose between two alternative models: the fixed-effect model, and the random-effects model. While the fixed-effect model assumes that there is only one true effect size, the random-effects model states that the true effects also vary due to between-study heterogeneity. This chapter describes the idea behind the fixed ...
