This column continues to be good reading. The last issue is on presentation and calculation of probabilities, and how many people, including doctors, do not understand and properly convey to their patients the probabilities involved in testing. http://opinionator.blogs.nytimes.com/2010/04/25/chances-are/?pagemode=print

The calculation described here is sometimes called a 2 by 2 analysis: calculation of the true positives, false positives, true negatives and false negatives.
