##### Features & benefits

- Over 40% of the more than 2,300 exercises are new or revised.
- Technology tips now appear in most sections. These tips show how to use Minitab, Excel, the TI-84 Plus, and StatCrunch to solve a problem.
- A variety of review and assessment features conclude each chapter, including a Chapter Summary, Review Exercises, Quiz, and Test. Students also have access to four Cumulative Reviews throughout the text.
- Statistics instruction is more accessible when it is carefully formatted on each page with a consistent, open layout. This text is the first college-level statistics book to be written so that, when possible, its features are not split from one page to the next, resulting in a cleaner and clearer presentation.
- Real-life examples, exercises, and projects that help students picture the world using statistics
- Chapter Case Studies – Each chapter has a Case Study featuring actual data from a real-world context and questions that illustrate the important concepts of the chapter.
- Real Statistics - Real Decisions: Putting It All Together — This feature encourages students to think critically and make informed decisions about real-world data. Exercises guide students from interpretation to drawing of conclusions.
- Chapter Technology Projects — Each chapter has a Technology project using Minitab, Excel, and the TI-84 Plus that gives students insight into how technology is used to handle large data sets or real-life questions.
- The variety of real-life applications are representative of the majors of students taking introductory statistics courses. Applications are both authentic and accessible, so that statistics comes alive and appears relevant to students. View the text’s Index of Applications for a complete list.
