Participants were randomized to receive supported employment or treatment as usual ("Control"). Supported employment refers to a type of specialized interdisciplinary vocational rehabilitation designed to help people with disabilities obtain and maintain community-based competitive employment in their chosen occupation (Bond, 2004). A subset of simulated data from this study are presented in HW5.sav. The independent variable in this example is treatment group (Supported Employment Vocational Rehabilitation Versus Control), and the dependent variable was the amount of weekly wages earned post-treatment. The null hypothesis is "There is no difference between the treatment and control groups in post-treatment weekly wages earned among veterans with spinal cord injuries."H Name Type Width Decimals Label Values Missing Columns Align Measure Role 1 ID String 2 0 Participant ID None None 6 Left Nominal Input 2 Group Numeric 8 0 Treatment Gr... {1, Control...
