Research Methods in Physical Activity, Eighth Edition, systematically guides students through the research process, introducing research methods, tools, and analysis techniques specifically for kinesiology and exercise science disciplines, including the subdisciplines of physical therapy, rehabilitation, and occupational therapy. The eighth edition continues its legacy with the authors’ trademark humor and is now enhanced with a new full-color layout. This reputable text provides step-by-step information for every aspect of the research process. Part I presents an overview of the research process, from preparing the research plan to understanding ethical issues in research and writing. Part II introduces statistical and measurement issues in research. Part III presents various approaches to research and methodology—including qualitative, quantitative, and mixed methods—while scholarly contributors offer advice for addressing sociohistorical, experimental, epidemiological, and philosophical research questions. Part IV details how to develop and organize research papers and presentations, and it includes guidance for describing results for publication in a scientific journal. Statistical tables and guides are available in the appendix.
