This dataset is designed for teaching partial or hierarchical regression (not to be confused with hierarchical linear modeling (HLM), which is an entirely unrelated method). The dataset is a subset of the 1996 Add Health Wave II, and the example models the association between weight and sleep, controlling for age, sex, and height. The dataset file is accompanied by a Teaching Guide, a Student Guide, and a How-to Guide for SPSS.
