If you're using Powerpoint, you might want to make a slide that says something like:

2,999 negatives -> 1% test positive -> 30 false positives

1 positive -> 99% test positive -> 1 true positive

So out of 31 positive tests, only 1 person has SDS.

If you've got the time, use a little horde of stick figures, entering into a testing machine and with test-positive results getting spit out.
