You are interested in conducting a survey at your school to determine if gender or ethnicity is related to perceptions about educational opportunity. the school has 1,800 students but you only have resources to interview 100. the student body is approximately equally divided between males and females. twelve percent of the school's population is asian american, 8% is african american, 10% is native american, and 70% is caucasian. you are interested in being able to generalize the results of your survey to the entire student body.
describe a technique for obtaining a sample of size 100 that would have a reasonable chance of producing results that could be generalized to the entire school.
suppose you sent the surveys out to classes and asked the students to complete them and return them to the main office. would the returns be likely to be biased in any direction? if so, why? in what direction?
suppose you decide to conduct the survey by personal interview. members of the student council, all of whom happen to be caucasian, will conduct personal interviews with the selected students. one of the survey questions reads, "do you agree or disagree with the following statement: all students, regardless of ethnicity, have equal opportunity to become part of student government." what potential bias is present in this question?
