PREFACEMany students in the behavioral sciences view the required statistics course as anintimidating obstacle that has been placed in the middle of an otherwise interestingcurriculum. They want to learn about human behavior—not about math and science.As a result, the statistics course is seen as irrelevant to their education and career goals.However, as long as the behavioral sciences are founded in science, knowledge of statisticswill be necessary. Statistical procedures provide researchers with objective and systematicmethods for describing and interpreting their research results. Scientific research is thesystem that we use to gather information, and statistics are the tools that we use to distillthe information into sensible and justified conclusions. The goal of this book is not onlyto teach the methods of statistics, but also to convey the basic principles of objectivity andlogic that are essential for science and valuable for decision making in everyday life.Those of you who are familiar with previous editions of Statistics for the BehavioralSciences will notice that some changes have been made. These changes are summarizedin the section entitled “To the Instructor.” In revising this text, our students have beenforemost in our minds. Over the years, they have provided honest and useful feedback.Their hard work and perseverance has made our writing and teaching most rewarding. Wesincerely thank them. Students who are using this edition should please read the section ofthe preface entitled “To the Student.”The book chapters are organized in the sequence that we use for our own statisticscourses. We begin with descriptive statistics, and then examine a variety of statistical proceduresfocused on sample means and variance before moving on to correlational methodsand nonparametric statistics. Information about modifying this sequence is presented in theTo The Instructor section for individuals who prefer a different organization. Each chaptercontains numerous examples, many based on actual research studies, learning checks, asummary and list of key terms, and a set of 20–30 problems.AncillariesAncillaries for this edition include the following.■MindTap ® Psychology: MindTap ® Psychology for Gravetter/Wallnau’s Statisticsfor The Behavioral Sciences, 10th Edition is the digital learning solution that helpsinstructors engage and transform today’s students into critical thinkers.
