You design a new test to measure psychopathy. You correlate your new test with the Psychopathy Checklist-Revised and the Levenson Self-Report Psychopathy Scale. You find that your test is highly correlated with these two previously designed tests. This is an example of what? A. Concurrent criterion validity B. Predictive criterion validity C. Convergent construct validity D. Divergent construct validity E. Content validity F. Internal validity

The Psychopathy Checklist – Revised (PCL-R) is an assessment tool used to identify psychopaths, with scores ranging from 0 to 40 (a score of 30 or higher being indicative of psychopathy). A forensic psychologist interested in the prevalence of psychopaths in a prison administered the PCL-R to 74 random prison inmates and obtained the following distribution of scores. Convert this into a grouped frequency distribution containing five class intervals, and (a) Determine the size of the class intervals, (b) Indicate the upper and lower limits of each class interval, (c) Identify the midpoint of each class interval, (d) Find the percentage for each class interval, (e) Find the cumulative frequency for each class interval, and (f) Find the cumulative percentage for each class interval. Score Value f 0-8 3 9-17 9 18-26 13 27-35 14 36-40 35 N = 74

For Exercises 3 through $12,$ use the Wilcoxon rank sum test. Assume that the samples are independent. Also perform each of these steps. a. State the hypotheses and identify the claim. b. Find the critical value(s). c. Compute the test value. d. Make the decision. e. Summarize the results. Use the traditional method of hypothesis testing unless otherwise specified. Lengths of Prison Sentences A random sample of men and women in prison was asked to give the length of sentence each received for a certain type of crime. At $\alpha=0.05,$ test the claim that there is no difference in the sentence received by each gender. The data (in months) are shown here. $$ \begin{array}{l|llllllll}{\text { Males }} & {8} & {12} & {6} & {14} & {22} & {27} & {32} & {24} & {26} \\ \hline \text { Females } & {7} & {5} & {2} & {3} & {21} & {26} & {30} & {9} & {4}\end{array} $$ $$ \begin{array}{c|cccc}{\text { Males }} & {19} & {15} & {13} & {} \\ \hline \text { Females } & {17} & {23} & {12} & {11} & {16}\end{array} $$
