College of Education and Human Development faculty member Dr. Jessaca Spybrook was recently awarded a three-year grant from the National Science Foundation entitled 鈥淧ower Analyses for Moderator and Mediator Effects in Cluster Randomized Trials.鈥 The purpose of the project is to improve the planning and design of multilevel studies throughout the social sciences by (1) developing power analysis formulas to estimate the probability with which a design can detect multilevel mediation and moderation effects if they exist and (2) implementing these formulas in software. The $799,688 grant is a collaborative research project with three Principal Investigators, Spybrook at 蜜桃社区 ($266,187), Professor Ben Kelcey at the University of Cincinnati ($289,949) and Professor Nianbo Dong at the University of Missouri ($243,552).
