Question

Research Summary All of the students in their final year of law school at the University of Memphis were sent an email asking them to participate in a research study. Forty law students volunteered for the study and provided informed consent. All of the participants observed a videotape of a crime. Next, a fair coin was flipped to decide if each participant would go to a room on the right or a room on the left. The twenty students in the room on the right attempted to choose the criminal seen in the movie from a lineup consisting of five people. The twenty students in the room on the left chose from a lineup consisting of ten people. Each of the subjects then judged their confidence in the person they selected as the criminal from 50% (no idea) to 100% (completely sure). Questions (Questions 4 – 6: Assume the results of the study show support for the researcher’s hypothesis.) 6. Statistical population generalizability: To what population will the researcher statistically be able to generalize his/her results? 7. Practical population generalizability: Practically, to what population might the researcher be able to generalize his/her results? Justify your answer and note any limitations to the study in terms of practical population generalizability. 8. Situational generalizability: To what situations might the research be able to generalize his/her results? Justify your answer and note any limitations of the study in terms of situational generalizability.
