Louise Fulkerson is president of the Student Marketing Association at Baylor University. Louise and the other officers want to conduct a short survey to determine the type of programming they should offer for the upcoming year. Their population is defined as "students in the College of Business." One of the officers suggests that each of them go into their classes, mostly seniors, and conduct the survey. "We can do it easily and fast, and our professors will be glad to help the association out by giving us a few minutes to conduct the survey," says one of the officers. But Louise is worried about the sample. "Most of us are marketing majors and we are all seniors taking senior classes. I would prefer to ask the Department Chairperson if we can survey students taking Fundamentals of Marketing because all majors have to take this course, and most of the future members of the Association will be coming from these Fundamentals classes." Louise is suggesting which one of the following sampling methods?A) quota sampleB) purposive sampleC) stratified sampleD) representative sampleE) systematic sample
