Just Checking exercises within each chapter allow students to pause and confirm their understanding of key concepts before moving on. These questions provide a quick check and most involve very little calculation. The answers are the end of each chapter so students can easily check their work. New exercises have been added throughout the book, and they have been graded by level of difficulty to give students additional practice with basic skills before applying them to more complicated problems. Exercises continue to be paired so that for every odd number, there is a similar even number, which gives students more comprehensive practice and teachers greater flexibility when assigning homework. What Have We Learned? sections at the end of each chapter highlight new concepts, define the new terms introduced in the chapter, and list the skills that the student should have acquired. This practical study guide ensures that students are fully prepared for exams. ActivStats Pointers highlight concept videos, teaching applets, and animations in ActivStats that enhance the discussions in the book.

ActivStats with Data Desk statistical software is included with every new copy of the text. ActivStats for JMP®, Excel®, Minitab®, and SPSS® is also available for bundling with this textbook. A motivating example starts off each chapter, teaching students how to Think about the statistical issues at hand, Show proper application of statistical techniques, and Tell others what they have learned. This "Think, Show, Tell" approach to problem solving is repeated throughout the book. Math Boxes give students easy-to-follow discussions of the underlying mathematics behind statistics. While the authors don't bury students in proofs and derivations, they do show that the formulas and procedures that they use stand on solid ground. What Can Go Wrong? sections in each chapter illustrate the most common misuses and misconceptions of statistical thinking to arm students with the ability to detect statistical errors and offer practice in debunking misuses of statistics. The book is organized into short, teachable chapters .

Each chapter covers roughly the material for one or two classes (depending on class schedule and length). Easy-to-read TI Tips show students how to use the calculator's statistics functions as they are needed. By Hand boxes appear occasionally throughout the text to show students how to do a calculation by hand. Reality Checks ask students to check that their results make sense in the context of the problem before interpreting the results, reminding them that Statistics is about understanding the world with data. Notation Alerts emphasize the importance of clear communication while demonstrating that proper notation is part of the vocabulary of Statistics. End-of-chapter features test students' understanding of the material and help them prepare for exams: A review of Key Concepts and essential Skills helps students check their own understanding, and Connections sections tie current material to concepts covered in previous chapters. on the Computer sections give generic output and instruction for several of the most common statistical software packages including: Data Desk®, Excel®, SPSS®, JMP® MINITAB®, and the TI-83/84 Plus graphing calculator.
