Hedberg, E. C.; Hedges, Larry – Society for Research on Educational Effectiveness, 2017
The purpose of this paper is to showcase new research that seeks to provide guidance on the heterogeneity of treatment effects by utilizing the variance of demographic differences in state assessments. This study is focused on a simple randomized block design where students are nested within schools, and within each school students are randomized…

Hedberg, E. C.; Hedges, Larry V. – Grantee Submission, 2014
Randomized experiments are often considered the strongest designs to study the impact of educational interventions. Perhaps the most prevalent class of designs used in large scale education experiments is the cluster randomized design in which entire schools are assigned to treatments. In cluster randomized trials (CRTs) that assign schools to…

Hedges, Larry V.; Hedberg, E. C. – Evaluation Review, 2013
Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

Vu, Maihan B.; Murrie, Dale; Gonzalez, Vivian; Jobe, Jared B. – Health Education & Behavior, 2006
As part of the formative assessment for the Trial of Activity for Adolescent Girls (TAAG), a multicenter study to reduce the decline of physical activity in adolescent girls, girls and boys with diverse ethnicity from six states participated in focus groups and semistructured interviews. Data from 13 girls' focus groups (N = 100), 11 boys' focus…
