(SPSS) A criminal psychologist wants to examine the level of narcissistic personality traits between those who are diagnosed with antisocial personality disorder (ASPD) and those who do not qualify for ASPD. She administers a measure of narcissistic personality traits where higher scores indicate higher levels of narcissism and scores range from 0–35.

a. Create a new SPSS data file for these scores. Your file must have 2 variables: diagnosis and score. Your diagnosis variable must be set up as a 1-column grouping variable with 2 groups (diagnosis, no diagnosis) coded numerically. This will be much like the gender variable you created in a previous module/week. For example, if you code ASPD Diagnosis as 1 and No ASPD Diagnosis as 2, then the SPSS file will appear somewhat like the following:

Column 1

Column 2

“Diagnosis”

“Score”

1

23

19

All ASPD Diagnosis scores from the table above will appear in a similar fashion.

Then, enter No ASPD Diagnosis information as:

2

Continue in this fashion to the end of the file.

b. Compute descriptive statistics by diagnosis (that is, for each of the two groups in one table) using similar steps to those covered in Green and Salkind’s Lesson 21 and in the Module/Week 3 presentation (HS GPA scores by Gender). Paste this into your homework document.

c. Construct a boxplot to show the difference between the mean scores of the 2 groups.
