The effect of viewing mug-shots on the accuracy of eyewitness identification was investigated. Twelve subjects observed a videotape of six men who they were later asked to identify in a recognition test. The subjects were randomly assigned to one of two groups. Subjects in Group 1 searched through a sequence of 75 mug-shots to identify the subjects, and subjects in Group 2 spent an equivalent amount of time looking for articles about crime in Time magazine. Following this, subjects were shown pictures that included the suspects and asked to identify them. The dependent variable is the number of suspects identified. The following data were obtained. Complete the appropriate t-test using the .05 level of significance and a two-tailed test. Write your null and alternative hypothesis. Write your conclusions with all three pieces (Reject/Fail to Reject, Data Report, and Written Conclusion linked to Scenario). Run any necessary post-hoc tests and report those conclusions. Using the information from the print out determine the Cohen's d, 12. n2. . w, or other effect size as appropriate with interpretations. Group 1 Group 2 5 6 4 4 5 1
