Aloe, Ariel M.; Becker, Betsy Jane – Journal of Educational and Behavioral Statistics, 2012
A new effect size representing the predictive power of an independent variable from a multiple regression model is presented. The index, denoted as r[subscript sp], is the semipartial correlation of the predictor with the outcome of interest. This effect size can be computed when multiple predictor variables are included in the regression model…

de Boer, Hester; Donker, Anouk S.; van der Werf, Margaretha P. C. – Review of Educational Research, 2014
This meta-analysis examined the influence of attributes related to the implementation of learning strategy instruction interventions on students' academic performance, and also examined how the attributes related to the method of testing the intervention effects affected the actual effects measured. Using metaregression, we analyzed the…

Kim, Rae Seon – ProQuest LLC, 2011
When conducting a meta-analysis, it is common to find many collected studies that report regression analyses, because multiple regression analysis is widely used in many fields. Meta-analysis uses effect sizes drawn from individual studies as a means of synthesizing a collection of results. However, indices of effect size from regression analyses…

Li, Andrew; Bagger, Jessica – Educational and Psychological Measurement, 2007
The Balanced Inventory of Desirable Responding (BIDR) is one of the most widely used social desirability scales. The authors conducted a reliability generalization study to examine the typical reliability coefficients of BIDR scores and explored factors that explained the variability of reliability estimates across studies. The results indicated…

Lynch, Kathleen Bodisch – 1986
Educational programs and evaluations which were submitted to the Department of Education's Joint Dissemination Review Panel (JDRP), in order to be named validated programs, were studied to identify program characteristics associated with large versus small effect size. Effect size was calculated for 165 out of 232 submittals reviewed by JDRP from…
