Experiment Designs of Educational Research Studies
Sat, April 10, 2:30 to 4:00pm EDT (2:30 to 4:00pm EDT), Division D, Division D - Section 2 Paper and Symposium SessionsSession Type: Paper Session
Abstract
The following session tackles experimental design questions with particular emphasis on how covariates impact design and analysis. Papers in this session provide insights into mediating and moderating covariates and discuss the impacts they have on the robustness analyses (e.g., power, effect size, bias, standard error). Further, this session pays particular attention to the roles these covariates play when implementing studies with longitudinal designs and provides recommendations for practice.
