WebIn fact, it is also possible (perhaps rarer) to see a large estimated effect size without there being statistically significant evidence it isn't zero. The issue is that your effect size is just a point estimate and hence is a random variable that depends on the particular sample you have available for analysis.

WebIf the original statistics was a correlation, just report the correlation. It already is a measure of effect size. To explain them in plain English, I would refer to Cohen's table of effect size magnitudes. For correlations, it says: <.10: trivial.10 - .30: small to medium.30 - .50: medium to large >.50: large to very large WebThe Cohen’s d effect size is immensely popular in psychology. However, its interpretation is not straightforward and researchers often use general guidelines, such as small (0.2), medium (0.5) and large (0.8) when interpreting an effect. Moreover, in many cases it is questionable whether the standardized mean difference is more interpretable ...

WebCohen’s D is the effect size measure of choice for all 3 t-tests: the independent samples t-test, the paired samples t-testand the one sample t-test. Basic rules of thumb are that8 d = 0.20indicates a smalleffect; d = 0.50indicates a mediumeffect; d = 0.80indicates a largeeffect. For an independent-samples t-test, Cohen’s D is computed as
