The second edition of Research Methods for Criminology and Criminal Justice is a core text for criminology and criminal justice research methods courses. This text offers a general foundation of knowledge that transcends particular topics or subject areas, allowing students to apply the methods and concepts discussed to a multitude of scenarios. Within the first five chapters, students learn (a) the philosophy behind scientific research, (b) the role of theory and hypotheses in the research process, © ethical issues in conducting research in our field, and (d) how research reports are structured. Thereafter, each new chapter will add information and examples that help students move toward a further understanding of research design and methodology that can be applied across the social and behavioral sciences to better understand social phenomena.
