• Substance abuse problem severity at time of admission into program (measured using a continuous 100-point scale with higher scores indicating higher levels of addiction);
• Sex (1 = male; 0 = female);
• Primary drug of choice (1 = methamphetamine; 2 = heroin; 3 = cocaine/ crack; 4 = marijuana; 5 = alcohol; 6 = other and
• Five year recidivism outcome (measured using days to re-arrest - 1826 days given if they were not re-arrested).

To conduct their analysis, the researchers decided to run the model using ______. Prior to running the analysis, the researchers had to recode the primary drug of choice variable into _____ dummy variable(s). In order to assess whether or not the full model was significantly associated with recidivism, the researchers looked at the p-value of .047. The researchers concluded that the overall model was ______. The _______ value of 0.40 indicates that we have explained 40% of the variability in the dependent variable with our model. To determine whether initial substance abuse problem severity was significantly associated with recidivism after controlling for the other factors in the model, the researchers reported the _______ for the substance abuse problem severity variable and its associated p-value.
