Where R2is thesquared multiple correlation. Cramer’s φ or Cramer’s V method:Chi-square is the best statistic to measure it for nominal data. In nominal data, when a variable has two categories, then Cramer’s phi is the best statistic use. When these categories are more than two, the...
―R2 *100%‖ is percent variance of the outcome y that can be explained by the linear regression model (i.e. indicates how well the linear regression line fits the data) 12 Effect Size 2014/11/13 ZhaoMF Cohen’s f2 – Used in multiple linear regression, – Standardized effect size is...
In the second step, multiple regression was used to work out the moderating effect. If the Bayesian information criterion of the two-level regression model is smaller than that of the multiple regression, the result of the two-level regression model and the corresponding effect size should be ...
Effect Size One way of measuringeffect sizeis to use the basic approach in Section8.1.1. For the situation at hand, the strategy is to measure the projection distance of thenull vector(0,…,0)to the estimate of the difference scoresθ1,…,θL. This measure ofeffect sizehas, approximately...

In practice, to calculate the number of schools needed to conduct a cRCT with a pre-specified significance level and statistical power to test for an intervention effect, multiple pieces of information are required. Besides the desired significance level, power, and effect size, numerical ...
packages provide only a limited number of effect-size estimates (e.g., η 2 but not f 2 Þ. The use of multiple regression to estimate moderating (i.e., interaction) effects of categorical variables involves an ordinary least squares (OLS) regression equation that examines the relation- ...
