This module is part of a series produced at The Universtiy of Nevada at Reno for the National Numeracy Network under a grant from the Woodrow Wilson Fellowship Foundation through the National Council on Education and the Disciplines. These brief modules are envisioned as a resource for teachers to use in a classroom setting and also for quantitative literacy workshops for teachers. Each module typically contains one or two examples related to "real world" quantitative literacy issues and includes exercises for students. There is also a section "for the instructor" that contains discussions of some of the topics, solutions to the exercises, and resources for further explorations.


Medical Testing

Jerry Johnson
Universtity of Nevada, Reno

This module explores issues in medical testing. No test is likely to be 100 percent perfect. The best that we can hope for is that it will give a correct answer with a very high probability. As we will see, the probabilities and percentages can lead to some surprising conclusions.

The concepts in this module are fairly subtle and may require some effort for many students to grasp. However, it may help to dispel misconceptions that people have about medical testing, and simply realizing the existence of these issues can be of value to a consumer.

The math includes percentages and probabilities.
