Second Edition


January 2025 | 672 pages | SAGE Publications, Inc
The Second Edition of Psychology Research Methods: How to Think About and Write About Research by Wendy Heath engages students with compelling studies relevant to students’ lives, but in a research methods context. By looking beneath the conclusions of these studies to determine which methods they use, students discover the relevance and importance of research methods. Heath also focuses on writing about research methods by presenting examples from across psychology literature as well as writing exercises at the end of each chapter. These features help students complete their research papers with confidence while gaining a greater understanding of research methods through writing. Covering descriptive, experimental, quasi-experimental, small-N design, and qualitative methods in psychology, this comprehensive guide gives students a broad overview of all methods in this clear text.
