As the authors write in the preface, “Data is messy, and statistical tools are imperfect. But, when you understand the strengths and weaknesses of these tools, you can use them to learn about the real world.” This book is full of examples and exercises on topics of current interest pulled from the popular media and published research.

In addition to the exercises at the end of each section and chapter, a novel feature is the incorporation of in-chapter exercises, meant to be done immediately, with answers below in the footnotes.
