Research Methods and Statistics in Psychology

The new edition of this market-leading textbook has been updated and revised to embrace current developments in this area of psychology. It remains a comprehensive survey of research methods in psychology today, with clear and detailed explanations of statistical concepts and data analysis. It also covers the full range of experimental and non-experimental methods and explores the ongoing quantitative-qualitative debate among researchers. It reexamines issues surrounding validity--including confounds, quasi, field, and non-experiments, and includes a new section on ethnographic methods.
