SPSS
Instructions
This assignment includes two problem sets that contain research scenarios and related questions.
For each scenario, you will respond to a series of questions asking you to create and interpret various tables and charts in SPSS. Paste your SPSS output directly into the homework underneath each relevant question. Type written answers into the document underneath the question to which they relate.
This assignment is worth 60 points.
Please review the SPSS Homework Tutorial in this module for directions on how to enter data in SPSS and use it to produce the final product for your assignment. The scenarios begin on the next page.
Problem Set 1: A forensic psychologist wants to examine the level of narcissistic personality traits in those who are diagnosed with antisocial personality disorder (ASPD) and those who do not qualify for ASPD within a local prison population. She administers a measure of narcissistic personality traits where higher scores indicate higher levels of narcissism and scores range from 0–35. Name your variables in Variable View. Assign values to the “Diagnosis” variable as follows: 1 = ASPD; 2 = no ASPD.

Using the data in the table above, set up your data file in SPSS and create a table of Descriptive Statistics using the “Explore” function that shows descriptive statistics for ASPD and no ASPD diagnoses separately. Paste the table here: (8 pts)
What is the standard deviation of narcissism scores in the ASPD group? (4 pts)
Compare the means of each group (ASPD and no ASPD). What can you say about the narcissism scores of the ASPD group compared to the no ASPD group? (5 pts)
Using the same data, create a boxplot in SPSS to show the difference in narcissism scores between the two diagnostic groups. Paste the boxplot here: (7 pts)
Based on the boxplot and descriptive statistics, which group shows more variability in narcissism scores? Support your answer with knowledge from the presentations and/or reading from this week. (6 pts)
