Designed for upper-level Research Methods in Health, HPER, Education, or Allied Health courses and can also be used as a supplement for Research in Nursing courses. This updated and revised new edition expands on its unique case study approach. Real-life cases open the methodologic and ethics chapters and are used throughout the chapters as the primary example. All of the case studies are health oriented in school, community, and hospital settings involving students, teachers, physicians, nurses, and health science researchers. New chapters on analytic epidemiology, descriptive data analysis, and sampling have been added to this edition.
