Preface xiii Exercises Many exercises require the interpretation of results. Great care has been taken to ensure their usefulness, relevance, and accuracy. Exercises are arranged in order of increasing difficulty and exercises are also divided into two groups: (1) Basic Skills and Concepts and (2) Beyond the Basics. Beyond the Basics exercises address more difficult concepts or require a stronger mathematical background. In a few cases, these exercises introduce a new concept. End-of-Chapter Features ■ Chapter Quick Quiz provides 10 review questions that require brief answers. ■ Review Exercises offer practice on the chapter concepts and procedures. ■ Cumulative Review Exercises reinforce earlier material. ■ Technology Project provides an activity that can be used with a variety of technologies. ■ Big (or Very Large) Data Projects encourage use of large data sets. ■ From Data to Decision is a capstone problem that requires critical thinking and writing. ■ Cooperative Group Activities encourage active learning in groups. Other Features Margin Essays There are 134 margin essays designed to highlight real-world topics and foster student interest. 36 of them are new to this edition. There are also many Go Figure items that briefly describe interesting numbers or statistics. Flowcharts The text includes flowcharts that simplify and clarify more complex concepts and procedures. Animated versions of the text’s flowcharts are available within MyMathLab for School. Formulas and Tables This downloadable resource, organized by chapter, gives students a quick reference for studying, or can be printed for use when taking tests (if allowed by the instructor). It also includes the most commonly used tables. This is available for download at www.TriolaStats.com, pearson.com/math-stats-resources, or from the MyMathLab for School course. Technology Integration As in the preceding edition, there are many displays of screens from technology throughout the book, and some exercises are based on displayed results from technology. Where appropriate, sections end with a new Tech Center subsection that includes new technology specific videos and detailed instructions for Statdisk, Minitab®, Excel®, StatCrunch, or a TI@83>84 Plus® calculator. (Throughout this text, “TI@83>84 Plus” is used to identify a TI-83 Plus or TI-84 Plus calculator). The end-of-chapter features include a Technology Project. The Statdisk statistical software package is designed specifically for this textbook and contains all Appendix B data sets. Statdisk is free to users of this book and it can be downloaded at www.Statdisk.org.
