You hypothesize that students in fraternities/sororities on your campus are more extroverted (on an introversion/extroversion scale) than other students. To answer your research question, you need to obtain a sample of "Greek" students and a sample of "independent" students. For each of these two populations of students, how would you obtain simple random samples using the four steps described in this chapter?

Question No 2:

For the hypothesis in question 1, describe how you would obtain samples using stratified random sampling, with stratification based on the sex of the student. Assume that 60% of the Greeks are women?

Question No 3:

For the hypothesis in question 1, describe how you would obtain samples using quota sampling based on the gender of the student. Again, assume that 60% of the Greeks are women?

Question No 4:

For the hypothesis in question 1, describe a poor method of sampling that you believe would result in systematic sampling error and thus bias the research findings. Explain why you believe the sample would be biased?
