Refer to the Experimental Psychology (January 2014) investigation of irrelevant facial similarity effects on judgment, Exercise 9.61. Recall that subjects (university students) were trained and then rated each of three different job applicants on a scale of 0 (not at all suitable) to 100 (very suitable). Each subject saw a picture of the applicant as well as a summary of the employee's application documents. All applicants were given average qualifications, but the applicants' pictures were morphed to look similar to a previous candidate who either had a low rating, a neutral rating, or a high rating. Job suitability scores for 10 subjects rating each of the 3 differently morphed candidates are reproduced in the table. Use a nonparametric procedure to determine if the distributions of job suitability scores differ for the three candidates. Test using α = .01.
