A study conducted at Stanford University in 2005 wanted to evaluate what percentage of students had used the drug Ecstasy. Two assistants were stationed on the main campus plaza and instructed to interview all students who passed through at specified times. As it turned out, 19% of 369 students interviewed said they had used Ecstasy at least once. Does the investigator’s procedure give a probability sample of Stanford students? Answer yes or no, and explain. If this is not a probability sample, what term best describes it?
