Statistics for the Behavioral Sciences

By far the best-selling introduction to statistics for students in the behavioral and social sciences, this text continues to offer straightforward instruction, accuracy, built-in learning aids, and real-world examples. The goal of STATISTICS FOR THE BEHAVIORAL SCIENCES, 8th Edition is to not only teach the methods of statistics, but also to convey the basic principles of objectivity and logic that are essential for science and valuable in everyday life. Authors Frederick Gravetter and Larry Wallnau help students understand statistical procedures through a conceptual context that explains why the procedures were developed and when they should be used. Students have numerous opportunities to practice statistical techniques through Learning Checks, examples, step-by-step Demonstrations, and problems. A strong ancillary package includes PowerLecture™, which contains lecture slides, JoinIn™ Student Response System content, and a computerized test bank; Enhanced WebAssign, a complete and easy-to-use homework management system; WebTutor™; an Instructor's Manual/TestBank, plus other online and print resources.

div class="aplus" br hr/ h2About This Edition/h2 pFrom the Publisher/p br/ h3New Features/h3 ul liThe 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). liChapters 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. liResearch examples have been updated throughout, and end-of-chapter problems have been extensively revised for currency and improved clarity. liThe 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. liThe 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. /ul h3Additional Features/h3 ul liiConceptual context:/i 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. liiAPA reporting guidance:/i 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. liiHelpful visuals:/i 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. /ul br/ hr/ h3See this title's supplement:/h3 piStudy Guide for Gravetter and Wallnau's "Statistics for the Behavioral Sciences"/i (Eighth Edition)/p br/ /div
