Research Methods, Statistics, and Applications

Third Edition

704 pages | SAGE Publications, Inc
The third edition of Research Methods, Statistics, and Applications by Kathrynn A. Adams and Eva K. McGuire consistently integrates the interrelated concepts of research methods and statistics to better explain how the research process requires a combination of these two elements. This best-selling combined text includes numerous examples and practical applications from the latest research across the social and behavioral sciences. The conversational tone and emphasis on decision-making engages students in the research process and demonstrates the value of rigorous research in academic settings and beyond. The end goal of this book is to spark students' interest in conducting research and to increase their ability to critically analyze research in their daily lives. The third edition includes a new chapter on measurement to better highlight the critical importance of this topic, updates for the 7th edition of the Publication Manual of the American Psychological Association, new examples related to social justice, a new section on case studies, and more thorough integration of research ethics information and tips throughout each chapter.

Key features


  • New chapter on Measurement tackles this critical topic with more depth so students can conduct more precise research.
  • APA Style Manual 7th Edition updates provide students with guidance on proper citation style, bias-free language, and report writing.
  • Additional sections on qualitative research emphasize case study research and other methods to help students complete their picture of research methods.
  • An updated, user-friendly SAGE companion website provides practice datasets, lecture slides, homework assignments, answers to statistics exercises, and test banks for instructors.


  • Thorough integration of research methods and statistics helps students gain a full picture of the research process.
  • Examples from current research literature provide a real-life context for understanding methods and statistics and demonstrate how a research topic can be examined in multiple ways.
  • Directions for calculating statistics using formulas, as well as data analysis programs (specifically SPSS and jamovi), enhance student understanding of analyses.
  • Ethics are discussed throughout the book— with tips for how to conduct ethical research in every chapter— to reinforce its importance in all stages of the research process.
  • Practice boxes in every chapter and end-of-chapter Review of Key Concepts provide repeated exposure to important ideas, as well as opportunities to apply concepts soon after learning about them.
  • A final “putting it all together” chapter provides a summary of the major questions to answer when designing and carrying out research.
  • A focus on academic honesty is woven throughout the book and reinforced in an APA-style research paper and published manuscript in the appendix. 

 We used the first and second editions in our own research methods and analysis courses for several years and with great success. Our students appreciated the conversational tone of the writing, the practice opportunities, and the applications of key concepts. Other professors who adopted or reviewed the previous editions commented positively about the writing style and organization, and the integration of current research. Many mentioned that they found the final “putting it all together” chapter to be a unique and important feature of the text. In writing this third edition, we aimed to build on and strengthen those aspects that students and professors found most useful.

The third edition includes new examples from the current research literature from psychology, criminal justice, politics, and education. We updated our citation and reference guidelines based on the 7th edition of the Publication Manual of the American Psychological Association (APA, 2020). We provide an annotated APA-style research paper and published manuscript in the Appendix that we updated with the 7th edition guidelines for this edition. A unique feature of the book continues to be a sustained focus on ethics, and as such we updated the language to be more inclusive and in line with new APA guidelines, added current examples relating to social justice, and integrated ethics tips within the chapter. Because measurement is such a critical part of research design, we reorganized material in the book and added a full chapter devoted to this topic. Although we continue to focus on quantitative analyses, we added a section on qualitative analyses as they relate to the case study. We also rearranged some chapters to improve the flow, updated the illustrations, and made a stronger connection with the companion Student Study Guide and IBM® SPSS® Workbook. For professors who are using jamovi instead, we created an alternative workbook for jamovi that is available on the instructor resource site.
