Introductory Statistics: Exploring the World Through Data, 2nd edition

About the Book

The writing style is relaxed and conversational and engages readers using language they can understand.

• Student guidance features appear throughout every chapter, ensuring that readers are following the material and making connections to their everyday lives:
• Snapshots go beyond a definition by breaking down the statistical concepts introduced in the text discussion, quickly summarizing the concept or procedure, and indicating when and how it should be used.
• A Theme opens each chapter, setting the tone and introducing the chapter's concepts.
• A Case Study opens each chapter, showing a real-world application of the concepts. At the end of the chapter, the case study is revisited to show how the statistical techniques covered in the chapter help solve the problem presented.
• Margin Notes draw attention to details that enhance learning and reading comprehension.
• Caution notes provide warnings about common mistakes or misconceptions.
• Looking Back reminders refer students to earlier coverage of a topic.
• Details clarify or expand on a concept.
• Key Points highlight essential concepts within the text to draw special attention to them. Understanding these concepts is essential for progress.
• The Chapter Review that concludes each chapter provides a list of important new terms, student learning objectives, a quick summary of the concepts and methods discussed, and sources for data, articles, and graphics referred to in the chapter.
• Technology integration emphasizes the use of statistical software, which allows readers to focus on learning the concepts rather than being bogged down with unnecessarily time-consuming number crunching.
• Check Your Tech shows students how to calculate a problem by hand using formulas and get the same result as statistical software.
• TechTips outline steps for performing calculations using TI-83/84-Plus^® graphing calculators, Excel^®, Minitab^®, and StatCrunch^®. Whenever a new method or procedure is introduced, an icon refers students to the TechTips section at the end of the chapter.
• Mathematical formulas are limited throughout the book, and are introduced only when necessary to understand a concept.
• Data sets used in the exposition and exercises, marked with an icon, are available at the textbook's web site and at www.pearsonhighered.com/mathstatsresources. Data sets are provided in multiple formats.
• An active learning focus keeps students engaged in the material.
• NEW AND UPDATED examples appear in each chapter, with current topics such as views of stem cell research (Chapter 7), online classes (Chapter 10), robots (Chapter 11), and Fitbit (Chapter 14). Many examples were also revised for a more thorough integration of technology.
• NEW! A wealth of exercises, including more than 500 new, revised, and updated exercises, appear at the end of each chapter, most using real data. Output from a range of statistical software is often included to acclimate students to interpreting results, regardless of which technology generated them.
• Guided Exercises step students through solving a problem if they need extra help while doing homework. These exercises are marked with an icon to indicate that step-by-step instruction is available in the Guided Exercises section at the end of the chapter.
• End-of-chapter exercises are organized by section and level of difficulty. Challenging exercises, identified with an asterisk, ask open-ended questions and sometimes require students to perform a complete statistical analysis.
• An abundance of worked-out examples model solutions to real-world problems that are relevant to students' lives. Each example is tied to an exercise (denoted with an icon in the exercise set) so that students can practice solving a similar problem.
• Exploring Statistics is an in-class activity intended to foster group work and hands-on exploration of statistics. There is one activity per chapter.
