WebEffect Size Interpretation. Finally, effectsize provides convenience functions to apply existing or custom interpretation rules of thumb, such as for instance Cohen’s (1988). Although we strongly advocate for the cautious and parsimonious use of such judgment-replacing tools, we provide these functions to allow users and developers to explore and … Webresults of studies using different designs and outcome measures (see, e.g. [12,24]). In one approach to systematic research review, effect sizes provide the basis of formal quantitative syntheses (see, e.g. [7]). There is substantial consensus on methods for computing effect sizes in between-subjects designs, and many ‘standard’ effect size
