9.  Researchers cannot observe behaviors of interest continuously because it would be too costly.  As a result, they create blocks of time to study the behaviors and hope that the behavior in those blocks presents an accurate picture of what happens during non-observation times.  Researchers have investigated optimal ways of using sampling blocks in observational research.  How accurate are conclusions drawn from small, medium, and large samples of observations and with random versus cluster sampling?

10.  How do ethological and randomized clinical trials differ in the study of psychiatric patients?  What are the advantages and disadvantages of each?

11. What are the ethical issues associated with studying people who may or may not know they are being observed?  Sometimes the issues are ambiguous.  Give an argument that the observation done in the research by Humphreys in The Tearoom Trade was ethical; then give an argument as to why it might be unethical.
