This SAGE Research Methods Dataset example provides the rationale for centering variables and illustrates the use of centering in the context of multiple regression with interactions (the topic of another SAGE Dataset example) using a subsample of the High School and Beyond Study, which is a nationally representative, longitudinal study of 10th and 12th graders in the US in 1980. The dataset file is accompanied by a Teaching Guide, a Student Guide, and a How-to Guide for SPSS
