Barry, Adam E.; Szucs, Leigh E.; Reyes, Jovanni V.; Ji, Qian; Wilson, Kelly L.; Thompson, Bruce – Health Education & Behavior, 2016
Given the American Psychological Association's strong recommendation to always report effect sizes in research, scholars have a responsibility to provide complete information regarding their findings. The purposes of this study were to (a) determine the frequencies with which different effect sizes were reported in published, peer-reviewed…

Skidmore, Susan Troncoso; Thompson, Bruce – Educational and Psychological Measurement, 2010
The purpose of the present study is to provide a historical account and metasynthesis of which statistical techniques are most frequently used in the fields of education and psychology. Six articles reviewing the "American Educational Research Journal" from 1969 to 1997 and five articles reviewing the psychological literature from 1948 to 2001…

Zientek, Linda Reichwein; Thompson, Bruce – Research in the Schools, 2010
Self-efficacy and mathematics anxiety have been identified as predictors of mathematics achievement. In the present study, secondary analyses on matrix summaries available from prior published studies were utilized to investigate the contribution that self-efficacy and mathematics anxiety made in mathematics performance. Commonality analyses were…

Thompson, Bruce – Middle Grades Research Journal, 2009
The present article provides a primer on using effect sizes in research. A small heuristic data set is used in order to make the discussion concrete. Additionally, various admonitions for best practice in reporting and interpreting effect sizes are presented. Among these is the admonition to not use Cohen's benchmarks for "small," "medium," and…

Zientek, Linda Reichwein; Thompson, Bruce – Educational Researcher, 2009
Correlation matrices and standard deviations are the building blocks of many of the commonly conducted analyses in published research, and AERA and APA reporting standards recommend their inclusion when reporting research results. The authors argue that the inclusion of correlation/covariance matrices, standard deviations, and means can enhance…

Thompson, Bruce – Psychology in the Schools, 2007
The present article provides a primer on (a) effect sizes, (b) confidence intervals, and (c) confidence intervals for effect sizes. Additionally, various admonitions for reformed statistical practice are presented. For example, a very important implication of the realization that there are dozens of effect size statistics is that "authors must…

Thompson, Bruce – Third Education Group Review, 2006
Value-added models, which rate schools for effectiveness while taking into account the poverty and other socioeconomic status of the students, are generating increased interest. This paper describes the use of one such model to evaluate whether school ratings changed when three new programs were introduced: the "Target Teach" curriculum…

Vacha-Haase, Tammi; Thompson, Bruce – Journal of Counseling Psychology, 2004
The present article presents a tutorial on how to estimate and interpret various effect sizes. The 5th edition of the Publication Manual of the American Psychological Association (2001) described the failure to report effect sizes as a "defect" (p. 5), and 23 journals have published author guidelines requiring effect size reporting. Although…

Snyder, Patricia; Thompson, Bruce; McLean, Mary E.; Smith, Barbara J. – Journal of Early Intervention, 2002
Findings are reported related to the research methods and statistical techniques used in 450 group quantitative studies examined by the Council for Exceptional Children's Division for Early Childhood Recommended Practices Project. Studies were analyzed across seven dimensions including sampling procedures, variable selection, variable definition,…

Thompson, Bruce – Educational Researcher, 2002
An improved quantitative science would emphasize the use of confidence intervals (CIs), especially CIs for effect sizes. This article reviews definitions and issues related to developing these intervals. CIs for effect sizes are especially valuable because they facilitate meta-analytic thinking and interpretations of intervals via comparison with…

Thompson, Bruce – Journal of Experimental Education, 2001
Asserts that editors should declare their expectations publicly and expose the rationale for editorial policies to public scrutiny. Supports effect size reporting and the reporting of score reliabilities. Argues against stepwise methods. Also discusses the interpretation of structure coefficients and the use of confidence intervals. (SLD)

Kieffer, Kevin M.; Reese, Robert J.; Thompson, Bruce – Journal of Experimental Education, 2001
Investigated the patterns of statistical usage and reporting in 756 articles published in the "American Educational Research Journal" (AERJ) and the "Journal of Counseling Psychology" (JCP) over 10 years. Evaluated the analytic practices used. Also discusses changes that may be necessary to improve statistics in behavioral…

Thompson, Bruce – 1998
This paper provides an introduction to basic issues concerning structural equation modeling (SEM), a research methodology increasingly being used in social science research. First, seven key issues that must be considered in any SEM analysis are explained. These include matrix of associations to analyze, model identification, parameter estimation…

Thompson, Bruce – 1982
A "doubly-centered" raw data matrix is one for which both columns and rows have both unit variance and means equal to zero. The factor scores from one analysis are the same as factor pattern coefficients from the other analysis except for a variance adjustment. This study explored an extension of the reciprocity principle which may have…

Thompson, Bruce; Snyder, Patricia A. – Journal of Counseling & Development, 1998
Investigates two aspects of research analyses in quantitative research studies reported in the 1996 issues of "Journal of Counseling & Development" (JCD). Acceptable methodological practice regarding significance testing and evaluation of score reliability has evolved considerably. Contemporary thinking on these issues is described; practice as…
