This comprehensive text explores the entire range of research methodologies in psychology (experimental and nonexperimental), using a programmatic approach to introduce topics and then build on earlier presentations to increase student understanding. Research concepts, rather than cookbook-like strategies, are emphasized in order to help students develop an understanding of scientific research. The research process is organized around a coherent descriptive model of research, and coverage of ethics and statistics is integrated throughout. Research Methods is accompanied by a CD-ROM that includes the student version of SPSS.
Each chapter concludes with “Chapter Summary” and “Review Exercises.”
