Combining Estimators in Interlaboratory Studies and Meta-Analyses
Peer reviewed Peer reviewed
Direct linkDirect link
Huang, Hening – Research Synthesis Methods, 2023
Many statistical methods (estimators) are available for estimating the consensus value (or average effect) and heterogeneity variance in interlaboratory studies or meta-analyses. These estimators are all valid because they are developed from or supported by certain statistical principles. However, no estimator can be perfect and must have error or…

Meta-Analysis of Scale Reliability Using Latent Variable Modeling
Peer reviewed Peer reviewed
Direct linkDirect link
Raykov, Tenko; Marcoulides, George A. – Structural Equation Modeling: A Multidisciplinary Journal, 2013
A latent variable modeling approach is outlined that can be used for meta-analysis of reliability coefficients of multicomponent measuring instruments. Important limitations of efforts to combine composite reliability findings across multiple studies are initially pointed out. A reliability synthesis procedure is discussed that is based on…

Variability in Measurement of Swimming Forces: A Meta-Analysis of Passive and Active Drag
Peer reviewed Peer reviewed
Direct linkDirect link
Havriluk, Rod – Research Quarterly for Exercise and Sport, 2007
An analysis was conducted to identify sources of true and error variance in measuring swimming drag force to draw valid conclusions about performance factor effects. Passive drag studies were grouped according to methodological differences: tow line in pool, tow line in flume, and carriage in tow tank. Active drag studies were grouped according to…

Henson, Robin K.; Kogan, Lori R.; Vacha-Haase, Tammi – 2000
Teacher efficacy has proven to be an important variable in teacher effectiveness. It is consistently related to positive teaching behaviors and student outcomes. However, the measurement of this construct is the subject of current debate, which includes critical examination of predominant instruments used to assess teacher efficacy. The present…

Gain Score in Item Response Theory as an Effect Size Measure
Peer reviewed Peer reviewed
Direct linkDirect link
Wang, Wen-Chung; Chyi-In, Wu – Educational and Psychological Measurement, 2004
Because of the requirement of reporting effect sizes and in the interest of measurement of change within the item response theory framework, their combination becomes a new issue. In the present study, repeated measures are decomposed as an initial ability and one or more modifiabilities (gain score) using a multidimensional Rasch model. The…

The Meta-Analytic Debate.
Bangert-Drowns, Robert L. – 1985
Since meta-analysis was described in 1976 (Glass) as the application of familiar experimental methods to the integration of available research, at least five coherent approaches to meta-analysis have appeared in common use. These approaches can be divided into two broad groups. In the first group (including procedures by Robert Rosenthal, Larry…
