Reseаrchers wоrking in the sоciаl sciences оften use surveys mаiled out to households to help identify cultural trends and behaviors. For one research study, the researchers acquired a list of all mailing addresses in a metropolitan area from a marketing company, then used a website that uses atmospheric noise to randomly select 1250 of those mailing addresses, one at a time. The researchers then sent surveys to each selected household and followed standard procedures to try to get as many responses as possible. What kind of sampling did the researchers use in this study?
