#1) Correctional Services Canada evaluated a nation-wide rehabilitation program. The program was intended for prisoners before their release, and its main purpose was to reduce recidivism (the proportion of the offenders who repeat their offenses within two years of their release). Admission to the program was voluntary. A total of 1000 inmates across the country enrolled in the program. Two years later, their numbers were compared with the general population of inmates. The results are summarised in the following table: Repeat offenders Non-repeat. Total All other inmates 2500 7500 10000 Program “graduates" 110 890 1000 a) Is this study observational or experimental? Explain. b) Is there any association between the program and recidivism? Explain. c) Can we conclude that the program reduces recidivism? Why?
