SummaryTypesOverviewInterpretationConfidence intervals by means of noncentrality parametersSee alsoFurther readingExternal linksAbout 50 to 100 different measures of effect size are known. Many effect sizes of different types can be converted to other types, as many estimate the separation of two distributions, so are mathematically related. For example, a correlation coefficient can be converted to a Cohen's d and vice versa. These effect sizes estimate the amount of the variance within an experiment tha… Large: 0.50 Small: 0.10 Medium: 0.30
