This Demonstration permits exploration of a famous dataset collected by Professor David Baldus involving the results of 100 Georgia criminal cases from arrests between March 1973 and June 1983 in which the death penalty was a potential punishment and there were eight explanatory variables. Defendants were arrested in Georgia between March 1973 and June 1983, convicted after trial of murder, and sentenced to life imprisonment or death. You may select the variables to be included in a multiple regression and see the power of those variables to explain any sentencing patterns.
