  1. Not-so-trivialQuiz!

  2. Offering college courses to prison inmates Exp(B) b What is the hypothesis? What is the “treatment” (i.e., the independent variable)? What is the dependent variable? What is the effect of “treatment” in percentage terms? [column Exp(B)] Is the effect statistically significant? At what level? Logistic regression

  3. What is the hypothesis? College degree reduces recidivism What is the “treatment” (i.e., the independent variable)? College degree (0=N 1=Y) What is the dependent variable? Recidivism (0=N 1=Y) Exp(B) b What is the effect of “treatment” in percentage terms?Earning a college degree reduced recidivism by 54.2 pct. [100%-45.8%, column Exp(B)] Is the effect statistically significant? At what level?Significant, .05 level (5 chances in 100 that the effect of earning a college degree is due to chance)

  4. What is the hypothesis? What are the main independent and dependent variables? How were they coded? What is the effect of PD=1 (Yes) for each model, in percentage terms?[Column Exp(B)] Is the effect statistically significant for each model? At what level? PD = Public defender Case dismissed Detained – no bail Convicted PD=1 (Yes)

  5. Public defenders produce worse outcomes for their clients than private lawyers • IV=Type of lawyer (Private=0, PD=1)DV=Case outcome (0=Favorable 1=Not) • (A) Defendants with public defenders are about 44 percent less likely to get cases dismissed than those with private lawyers (1.00-.561)(B) Defts. with PD’s are about 158 percent morelikely to be detained pretrial(C) Defts. with PD’s are 77 percent morelikely to be convicted • Yes – all effects significant at .01 level Case dismissed Detained – no bail Convicted PD=1 (yes)
