Search the Web for a media account that involves statistical information. For example, you may be able to locate a report on a disease, a clinical trial, or a new medical device. Alternatively, if you do not have access to the Web, newspaper articles may cover similar topics. Sometimes advertisements for medicines present statistics. Select one media account and answer the follow- ing questions:
a. How were the data obtained?
b. Based on the information presented, do you think that the investigators used a descriptive or inferential approach?
c. If inferences are being drawn, what is the main question being addressed?
d. How was the sample selected? To what groups can the results be generalized?
e. Could the results be biased? If so, what are the potential sources of bias?
f. Were conclusions presented? If so, do you think they were warranted? Why or why not?
