Research Methods: A Process of Inquiry, 6/e This comprehensive text and companion website explore the entire range of research methodologies in psychology, using a programmatic approach to introduce topics and sequentially build on earlier presentations. Included are unique decision-tree flowcharts that lead students through the basic research designs to the choice of appropriate statistical procedures. Emphasizing research concepts rather than cookbook-like strategies, and using clearly written explanations and examples drawn from all areas of psychology, the Graziano/Raulin textbook, Research Methods: A Process of Inquiry, 6th edition, and website help students develop a sophisticated understanding of scientific research. In addition, because it is so important to teach students ethical sensitivity and skills, nearly every chapter deals with some aspects of research ethics, keeping the issues visible throughout the text.
