This quotation serves as the guiding rationale for this book and, I hope, provides an outlook for teaching and learning about statistics. From the main content to the ped- agogical aids and end-of-the-chapter exercises, this textbook fosters learning and dis- covery. As students learn how to perform calculations and interpret the results, they will discover new ways to think about the world around them, uncover previously unrec- ognized relationships among disparate variables, and make better judgments about how and why people behave the way they do. .
