Fix It
Clay is a graduate student who recently celebrated completing his first year of graduate school. The next day Clay felt terrible. This leads him to wonder what the best hangover remedy is. He begins by asking a few of his friends what has worked for them. One friend says a heavy, greasy meal always makes him feel better. Another friend says she takes ibuprofen and pink bismuth. His roommate swears by lots of coffee. Clay decides to test these remedies empirically and his friends eagerly volunteer to participate in his study. Clay's friends consume drinks of their choosing until their blood alcohol content reaches 1.6, twice the legal limit of intoxication. The next day, he serves each of them bacon, eggs, hash browns, and pancakes. Two hours after they eat they complete a survey to assess how sick they feel. Sickness scores vary from 0 = not sick at all, to 50 = extremely sick. Clay repeats this procedure two more times with the same participants. On the second occasion he gives them ibuprofen and pink bismuth, and on the third occasion he serves them coffee.
Clay's research is not based on a review of the literature. What do you think about that? What type of research design did Clay create and how should he analyze the data? Do you see any limitations with his methods?
