Welcome to the Companion Website

A companion website for this book at https://edge.sagepub.com/liu1e contains resources for both instructors and students. The password-protected instructor site includes solutions to the end-of-chapter problems, and the datasets and R commands for the exercises. The open-access student site includes the datasets and R commands used in the book. The datasets are in the .dta format, one of the major data formats for the 2016 GSS. Other data formats, such as CSV, Excel, SAS, SPSS, and R have also been created for students and instructors, and made available on the website.
