e. What is the most appropriate level of IRB review for this scenario? Why?
2. Please indicate the unit of analysis for each scenario below:
A. A researcher was interested in how much coverage legislative events received in his local newspaper.

3. Suppose you were asked by the president of Virginia Commonwealth University to do a survey of the student body about fear of violence on campus. The president believes it is sufficient to stop students on their way to the library and hand out the questionnaire. You argue for a probability sample instead. Your argument should include a discussion comparing the benefits and costs of probability strategies versus non-probability strategies and an argument for why probability is better. However, also convey when non-probability sampling of those students on the way to the library, as suggested by the president, may be appropriate. (Minimum response word count= 150 words; Base your response on scenario given.)
