Question

Criminologists are studying a new program for rehabilitating criminals. The program will be considered successful if it results in fewer repeat offenses. Therefore, they decide to compare the number of repeat offenses committed by graduates of the new program with the number of repeat offenses committed by criminals who have not participated in the new program. They randomly select 40 graduates of the new program. To control for things like age and socioeconomic status, they carefully match each selected graduate with a nongraduate of the same age, socioeconomic status, and so forth. Is this an example of dependent sampling or independent sampling. Why?

Explanation / Answer

This is an example of Dependent sampling. Because they select two groups in which each selected graduate with a nongraduate of the same age, socioeconomic status, and so forth. It means graduate is chosen for one sample directly influences the choice of a nongraduate for the other sample. So it is dependent sampling.
