n this assignment, you will use the "Data Week 3c.sav" data file. These data represent the results of a fictitious study which investigates three different treatments for the reduction of occupational stress - a progressive muscle relaxation (PMR) technique, a biofeedback technique, and a meditation technique. The researchers want to determine which, if any, technique is most effective in the reduction of occupational stress. Employees were randomly assigned to the PMR, biofeedback, or meditation group. All employees were screened to ensure they met the criteria for high levels of occupational stress. All employees received a 1-hour training on either PMR, biofeedback, or meditation. After 1 month of utilizing the stress management technique, employees completed a measure of occupational stress called the Occupational Stress Inventory (OSI). Note that higher scores on the OSI inventory reflect greater levels of occupational stress
