Your criminal justice class requires a study of the success of your state’s drug courts. The professor suggests that you first select 10 counties from your state. From those 10 counties, you will select the two largest cities from each. Finally, the drug courts in each of the cities will be monitored to measure success. What type of sampling design did your professor suggest?
