Empirical Methods in Law Homework – Chapter 10 Robert M. Lawless Jennifer K. Robbennolt Fall Semester 2016 In NAACP v. City of Mansfield (page 224), the question was whether the court should issue a preliminary injunction based partly on the statistical evidence of the discriminatory hiring practices of the city's police and fire departments. The court characterized the chi-square statistic on the pass rate for the police department exam to be only marginally statistically significant. For the fire department, the data showed that of 10 black applicants only 1 passed the exam but that 38 of 86 white applicants had passed. Without looking up the case, can you calculate the chi-square statistic for these data? Should the court have used the chi-square statistic? If not, what statistic should it have used? In a recent study, one of our colleagues conducted a study of the “integrity” rationale for the exclusionary rule. The integrity rationale “counsels exclusion when the illegal search violates a cherished principle, such that introducing the evidence would ‘dirty the hands’ of the court that used it.” Our colleague asked law students and lawyers to take part in “a judicial role-playing exercise where they were induced at trial to either use dirty evidence (‘dirty hands’) or not use it (‘clean hands’). The main dependent measure was whether those in the ‘dirty hands’ condition were more likely to take, as a thank-you gift, a small bottle of alcohol based hand disinfectant (Purell) instead of a highlighter pen with Post-It flags in the barrel (Pen).” The output below is from a statistical program known as SPSS.
