Question description

Your assignment is to use this hemoccult test scenario as an example to communicate the

nature of a medical test to a lay person. (Think of a family member or a friend who is not

familiar with statistics.) You need to incorporate three elements in your essay:

1. Identify the base rate (or prevalence in medical literature), sensitivity (the

percentage of individuals with a disease who are correctly classified as having the

disease), and false positive rate in this case. Provide a brief and clear description

of these terms using your own words.

2. Calculate the probability that this person actually has colorectal cancer given a

positive test.

3. Based on your analysis, communicate your result to someone who thinks that

routine cancer screening tests for healthy persons are always a good idea.

Your essay will be scored based on your (1) interpretation, (2) calculation, and (3)

communication; see the attached rubric. But don’t simply do what the rubric tells you to

do. Be creative: up to 3 additional points are based on

effort, originality, or insight
