h = 0.20: "small effect size". h = 0.50: "medium effect size". h = 0.80: "large effect size". Cohen cautions that: As before, the reader is counseled to avoid the use of these conventions, if he can, in favor of exact values provided by theory or experience in the specific area in which he is working.
In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...
Hi all and especially Grant, Have you noticed that the current version of the article - the section on Cohen & r effect size interpretation - says that "Cohen gives the following guidelines for the social sciences: small effect size, r = 0.1 − 0.23; medium, r = 0.24 − 0.36; large, r = 0.37 or larger" (references: Cohen's 1988 book and 1992 ...
The last value listed, labelled “r2CU” is the pseudo-r-squared by Nagelkerke and is the same as the pseudo-r-squared by Cragg and Uhler. Pseudo-R-squared values are used when the outcome variable is nominal or ordinal such that the coefficient of determination R 2 cannot be applied as a measure for goodness of fit and when a likelihood ...

To gauge the research significance of their result, researchers are encouraged to always report an effect size along with p-values. An effect size measure quantifies the strength of an effect, such as the distance between two means in units of standard deviation (cf. Cohen's d), the correlation coefficient between two variables or its square ...
It's a universal size that fit just about any size tablet, phone or e-book. Plus, it includes a pocket on the side that can store small items you don't want to lose like your page turner.
The AUKUS nuclear-powered submarine partnership with Australia will benefit the United States and is the kind of "burden sharing" deal that President-elect Donald Trump has talked about, U.S ...
