With an organization following the sequence of planning and conducting a research investigation, this text emphasizes the need to study behavior using a variety of research approaches, with important concepts described in several contexts throughout the book. An overview of the scientific approach to knowledge and the distinction between basic and applied research is followed by chapters on research sources, ethics, experimental and nonexperimental approaches, and measurement issues. Later chapters cover different research methods and experimental design. Two chapters on understanding research results cover correlation and statistical inference, and a final chapter looks at generalizing results. Chapters are relatively independent to allow instructor flexibility. Key terms, review and activity questions, and answers are included. An appendix on writing research reports includes a sample paper. There is also an appendix on statistical tests, and a collection of statistical tables. Highlights of this tenth edition include revised material on validity of measurements, and updated structural equations models. Cozby is affiliated with California State University-Fullerton.
