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

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.

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

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.
