Find an experiment. You can find the latest medical research in the Journal of the American Medical Association at www.jama.ama-assn.org and the New England Journal of Medicine at www.nejm.org. Many of the articles describe randomized comparative experiments and use the language of statistical significance when giving conclusions. Look through the abstracts and find an experiment of interest to you. If your institution has a subscription to these journals, you should be able to view the entire article. Otherwise, use the information in the abstract to answer as many of these questions as you can. What was the purpose of the experiment? How many factors were in the experiment, and what were the levels of the factors? What response(s) were measured? How many subjects were assigned to each of the treatments, and was randomization used? Was it a double-blind experiment? What were the conclusions, and were the results statistically significant?
