This text uses the same conceptual, intuitive approach of Basic Statistics for the Behavioral Sciences, but eliminates extensive reference material and advanced or obscure statistical methods. Essentials presents only the procedures undergraduates need for reading research literature and conducting their own studies. New terms are integrated with more difficult concepts in an accessible, non-threatening format that provides concise explanations, creating a foundation and making further elaboration easier to understand.
Students learn more intuitively through examples drawn from everyday life, and virtually all involve specific variables and research questions instead of generic data. Once students review the learning goals for each chapter, they follow a focused structure that emphasizes understanding of general concepts and procedures, supported by Remember sections that recall calculations or interpretations of a statistic. Two-part end-of-chapter problems offer Review Questions, which require students to define terms and outline procedures; and Application Questions, which ask them to perform procedures, interpret their results, and critique others.A Quick Review sections revisit concepts, provide worked-out examples, and help students check comprehension through review questions.Chapter 12 presents a nonmathematical discussion of the two-way ANOVA and covers the concepts of collapsing, main effects, and interaction. Computations appear in a separate appendix.Computational formulas appear in color throughout each chapter and key terms are highlighted, reviewed in the chapter summary, and listed in a key terms section.Students can use summary tables and sections to organize and integrate the separate steps in previous sections; and review material in comprehensive chapter summaries.End-of-chapter material includes a summary of formulas, while comprehensive lists of formulas and symbols appear in the front and end matter of the text.A Word About sections include self-contained, brief descriptions of additional procedures that instructors can include or omit without affecting students' understanding of later chapters.
