“This is an appealing, accessible, and highly readable introductory quantitative research textbook. The authors provide clearly written, jargon-free explanations and examples drawn from various areas of psychology to enhance a sophisticated understanding of the research process.”

“This book offers a straightforward progression of concepts with direct application as students prepare their research project from beginning to end.”

This book provides a good introduction to research in Psychology. The best part is the conceptual exercises at the end of each chapter. They are very engaging and stimulate critical thinking. However the book only manages to cover the topics superficially and does not provide any in-depth information. Some important concepts such as research validity, sources of threat to validity and strategies for controlling them are not covered.
