A clear, concise guide to the tools and techniques of behavioral research, this updated second edition stresses a hands-on, multimethod approach to undergraduates in many fields of study. It covers both laboratory and field experimentation, and addresses questions that often confront beginners, such as how to conduct an interview, how to design a questionnaire, and how to make systematic observations of behavior. The book will give students a solid grounding in methods of observation, in experiment and survey design, and in techniques of sampling, statistics, and analysis.
