Part 3: Cumulative Homework
1. To investigate the relationship between a person’s commute time to work and general life stress, a health psychologist interviewed people about the time they spend in their daily commute to work (in minutes) and had them fill out the Perceived Stress Scale (PSS) (http://www.macses.ucsf.edu/research/psychosocial/pss10.php), with scores ranging from 0 (no perceived stress) to 10 (high perceived stress). Is there a significant relationship between time of commute and general life stress? Choose the correct test to analyze this question, set up the SPSS file, and run the analysis. Follow the directions under the table on the following page.
