The experimental stimulus of the research is the midnight basketball program itself, as it is the intervention being studied to determine its effectiveness in reducing juvenile crime. The crime rates in both the experimental (city with the program) and control (city without the program) groups are the outcome measures being compared, but they are not the experimental stimulus. The number of kids who take part in the program is a potential moderator variable that could affect the program's effectiveness, but it is not the experimental stimulus. The crime rate after the program was instituted is an outcome measure, similar to the crime rate before the program was instituted, and is not the experimental stimulus.
