About The Solution

Overview

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.


Additional Product Information

Features/Benefits

  • Excellent problems, straightforward writing—Gravetter and Wallnau are renowned for their excellent sample problems (Demonstrations), found at the end of every chapter, which walk students step-by-step through procedures in a variety of ways. This text is also consistently praised by professors and students alike for the friendly, accessible writing style.
  • Enhanced WebAssign makes it easy for you to assign, collect, grade, and record homework assignments via the web. This proven and reliable system offers hundreds of practice problems pulled directly from this text and its Test Bank, step-by-step tutorials for text examples, and simulation problems that help students build problem-solving skills. For more details, see the front pages of this text or visit www.webassign.net/wadsworth.
  • In-text learning aids—Students have many opportunities to assimilate the material and practice working through problems. Numerous Learning Checks (with answers) challenge students to test their comprehension as they read. A Focus on Problem Solving section in each chapter offers practical tips on deciding which formulas to use and cautions for avoiding common errors. Each chapter ends with 25 to 30 problems.
  • Conceptual context—To help make learning statistics as simple as possible for students 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 students. For example, a Statistics Organizer at the end of the text provides a decision tree to guide students to appropriate statistical procedures within the text.
  • Measurement of effect size—The measurement of effect size is included throughout the inferential statistics chapters (8, 9, 10, 11, 13, 14, 15, 16, and 18).
  • SPSS®—An appendix contains a general introduction to SPSS®. In addition, at the end of each chapter for which an SPSS analysis is feasible, a step-by-step set of instructions describes how to enter data, how to run the analysis, and what to look for in the output.

What's New

  • 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 students through statistical procedures in a variety of ways, have been simplified to focus on the content of the chapter rather than tedious computations.
  • Enhanced WebAssign is now offered. This proven and reliable system offers hundreds of practice problems pulled directly from this text and its Test Bank, step-by-step tutorials for text examples, and simulation problems that help students build problem-solving skills.
