About This Edition

From the Publisher

New Features

• The authors continue to refine and improve each edition, and this one is no exception. Content changes include an expanded discussion of continuous and discrete variables (Chapter 1), a new discussion relating measures of variability to the scales of measurement introduced in Chapter 1 (Chapter 4), and expanded coverage of z-scores, including increased emphasis on the definition and concept of z-scores rather than formulas (Chapter 5).
• Chapters 13 through 15 include greater emphasis on concepts and less on computation, and a significantly expanded Chapter 17 includes new material on the interpretation of multiple regression and partial correlations.
• Research examples have been updated throughout, and end-of-chapter problems have been extensively revised for currency and improved clarity.
• The chapter-opening Preview sections have been revised to emphasize the fact that each new statistical technique is intended to serve a specific purpose or solve a specific problem.
• The step-by-step Demonstration problems at the end of each chapter, which walk users through statistical procedures in a variety of ways, have been simplified to focus on the content of the chapter rather than tedious computations.

Additional Features

• Conceptual context: To help make learning statistics as simple as possible for users who may be intimidated by the subject, statistical formulas are presented in both standard mathematical notation and in everyday language, with explanations of how and why formulas are used.
• APA reporting guidance: In the Literature sections, which appear in nearly every chapter, demonstrate how statistical results (e.g., for the mean and the standard deviation, t tests, and independent-measures tests) are reported in APA style and explain the notation and jargon used.
• Helpful visuals: Summary charts and graphs throughout the text are lauded by instructors and users. For example, a Statistics Organizer at the end of the text provides a decision tree to guide users to appropriate statistical procedures within the text.
