13. The purpose of sampling is to select a set of elements from a population in such a way that the descriptions of the sample statistics accurately portray the parameters of the population. This is best achieved through use of:

14. In order to study active criminals who have not been arrested for their criminal acts, the researcher would be wise to employ which type of sampling technique?

15. Stratified sampling results in a greater degree of representativeness but at the same time increases the probable sampling error.

35. The way to remember the percentages of samples that will fall within one, two and three standard errors of the parameter are the following:

36. 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 ten 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?
