New to this Edition

NEW Complement your text and course content with study and practice materials. Cengage Learning's Statistics CourseMate brings course concepts to life with interactive learning, study, and exam preparation tools that support the printed textbook. Watch student comprehension soar as your class works with the printed textbook and the textbook-specific website. Statistics CourseMate goes beyond the book to deliver what you need!

NEW More than 200 new and revised problems that feature basic computations, interpretation, and reinforce statistical literacy. Basic computation problems focus student attention on relevant formulas, requirements, and computational procedures. After practicing these skills, students are more confident as they approach real-world applications.

NEW The Looking Forward feature shows students where the presented material will be used later and motivates them to pay extra attention to key topics.

NEW Interpretation problems ask students to explain the meaning of statistical results in the context of a particular application.

NEW Expand Your Knowledge problems present the geometric mean and the harmonic mean (Section 3.1), moving averages (Section 3.2), correlation of averages (Section 4.2), odds for and odds against (Section 5.1), uniform probability distribution (Section 7.1), plus four method for confidence intervals (Section 8.3), probability of two confidence intervals (Chapter 8 review), and serial correlation (Section 11.4).

Section 2.1 now includes a discussion of cumulative frequency and ogives.

Examples in Probability (Chapter 5) have been revised to incorporate sample spaces that are small and easy for students to visualize.

REVISED Tech Notes throughout the text give students helpful hints on using TI-84 Plus and TI-Nspire (with 84 Plus keypad) and TI-83 calculators, Microsoft Excel 2010, and MINITAB to solve a problem. They include display screens to help students visualize and better understand the solution.

REVISED Using Technology instructions are available at the end of each chapter in the Using Technology section. Problems are presented with real-world data from a variety of disciplines that can be solved by using TI-84 Plus, TI-Nspire (with 84 Plus keypad) and TI-83 Plus calculators, Microsoft Excel 2010, MINITAB, and SPSS.

UPDATED Real-world applications are used from the beginning to introduce each statistical process. Rather than just crunching numbers, students come to appreciate the value of statistics through relevant examples.

REVISED Procedure display boxes summarize simple step-by-step strategies for carrying out statistical procedures and methods as they are introduced. Requirements for using the procedures are also stated. Students can refer back to these boxes as they practice using the procedures.

Throughout the Sixth Edition, examples, guided exercises, and problem sets feature interpretation, and address the suitability of using a specified statistical method or process for analysis.
