Case Problem: Hamilton County Judges

The data in the table provides the basis for the analysis. We provide notes as a guide to answering questions 1 through 5.

1. The conditional probabilities of cases being appealed in the three courts are given in the 3 Total rows in the table. For Common Pleas Court, the probability of an appeal is .0401; for Domestic Relations Court, the probability of an appeal is .00348; and for Municipal Court, the probability of an appeal is .00461. Appeals are much more likely in Common Pleas Court. But, even there, only 1 in 25 cases are appealed. The unconditional probability of an appeal across all 3 courts is

(1762 + 106 + 500)/(43,945 + 30,499 + 108,464) = .0129.

2. The probability of a case being appealed for each judge is given in column 5 of the table. Judges Winkler, Panioto and Grady have the lowest probability of appeal for Common Pleas, Domestic Relations and Municipal Courts respectively.

3. The probability of a case being reversed for each judge is given in column 7 of the table. Judges Winkler, Panioto and Grady/Hair have the lowest probability of reversal for Common Pleas, Domestic Relations and Municipal Courts respectively. These are the probabilities for reversal for all cases disposed of, not just the ones appealed.

Those rankings were the same as...
