This workshop will provide an introduction to multilevel modeling. Many social and natural phenomena have a nested or clustered organization that results in data with dependencies associated with group or cluster membership. Hierarchical Linear Models (HLM) provide a method for correctly analyzing such data as well as a means to study relationships that cross levels. Workshop participants will learn foundational principles and concepts in HLM and will have hands-on practice using software to apply and interpret basic models. The workshop will cover multilevel data structures, intraclass correlation, model building, centering, model testing, fixed and random effects, two and three level models, longitudinal growth models, statistical power and design planning, and the use of HLM in cluster randomized trials.[size=+1][size=+1]
