Baker, Rose D.; Jackson, Dan – Research Synthesis Methods, 2013
The use of meta-analysis in medicine and epidemiology really took off in the 1970s. However, in high-energy physics, the Particle Data Group has been carrying out meta-analyses of measurements of particle masses and other properties since 1957. Curiously, there has been virtually no interaction between those working inside and outside particle…

Donegan, Sarah; Williamson, Paula; D'Alessandro, Umberto; Tudur Smith, Catrin – Research Synthesis Methods, 2013
Background: Homogeneity and consistency assumptions underlie network meta-analysis (NMA). Methods exist to assess the assumptions but they are rarely and poorly applied. We review and illustrate methods to assess homogeneity and consistency. Methods: Eligible articles focussed on indirect comparison or NMA methodology. Articles were sought by…

Marsh, Herbert W.; Ludtke, Oliver; Nagengast, Benjamin; Trautwein, Ulrich; Morin, Alexandre J. S.; Abduljabbar, Adel S.; Koller, Olaf – Educational Psychologist, 2012
Classroom context and climate are inherently classroom-level (L2) constructs, but applied researchers sometimes--inappropriately--represent them by student-level (L1) responses in single-level models rather than more appropriate multilevel models. Here we focus on important conceptual issues (distinctions between climate and contextual variables;…

Rhemtulla, Mijke; Brosseau-Liard, Patricia E.; Savalei, Victoria – Psychological Methods, 2012
A simulation study compared the performance of robust normal theory maximum likelihood (ML) and robust categorical least squares (cat-LS) methodology for estimating confirmatory factor analysis models with ordinal variables. Data were generated from 2 models with 2-7 categories, 4 sample sizes, 2 latent distributions, and 5 patterns of category…

Blanton, Hart; Jaccard, James – American Psychologist, 2006
Reducing the arbitrariness of a metric is distinct from the pursuit of validity, rational zero points, data transformations, standardization, and the types of statistical procedures one uses to analyze interval-level versus ordinal-level data. A variety of theoretical, methodological, and statistical tools can assist researchers who wish to make…

Miller, Robert – Bulletin of the Council for Research in Music Education, 1989
Provides a nontechnical explanation of the family of multivariate statistical techniques known as multidimensional scaling (MDS). Explains the purpose of MDS, and the advantages of using these techniques in the study of musical perception. Discusses two approaches to the interpretation of MDS solutions. Lists examples of musical studies using MDS.…

Patelis, Thanos – 1996
The selection of supervision models from the point of view of practitioners has become overwhelming, especially within the contextual forces of a school or school system. The purpose of this study was to use multidimensional scaling (MDS) to describe four theoretical models of teacher supervision (clinical, artistic, technical, and reflective)…

Benson, Jeri; Zarnegar, Zohreh – 1984
The purpose of the study was to use confirmatory factor analysis techniques to assess the adequacy of previous validity studies related to the structural and theoretical dimensions underlying a measure of self-concept, the Piers Harris Children's Self Concept Scale. Responses from 890 students in grades 3-6 were used as input to the LISREL program…

Sparling, Joseph J.; And Others – 1977
In a series of three independent studies that focused on the classic sources of curriculum (the learner, society, and subject matter), data were gathered that might bear on the choices facing the curriculum developer. Learner data tentatively revealed what characteristics of pictures affected the deployment of third-grade children's visual…

Mok, Magdalena M. C.; McDonald, Roderick P. – 1993
The aim of this paper is to: (1) discuss the characteristics of seven bilevel factor models; and (2) arrive at a list of empirically based recommendations for selecting appropriate bilevel factor models, the assumptions underlying these decisions, and the consequences for interpretation of the Spearman case. The five models considered in the…

Wehmeyer, Michael L.; Garner, Nancy; Yeager, Danna; Lawrence, Margaret – Education and Training in Developmental Disabilities, 2006
The Individuals with Disabilities Education Act requires that States provide a free, appropriate public education to children with disabilities residing within that state between the ages of 3 and 21. The ages of 18 to 21 constitute a unique time for students with disabilities whose peers have left public schools for postsecondary education or…

Schaefer, Earl S.; And Others – 1985
This study replicates and elaborates a three-dimensional, spherical model that integrates research findings concerning social and emotional behavior, psychopathology, and academic competence. Kindergarten teachers completed an extensive set of rating scales on 100 children, including the Classroom Behavior Inventory and the Child Adaptive Behavior…
