Companion Slides: Using Test Information I

This glossary of terms supports the teaching pack on Using Test Information I, in which students review the four conditional probabilities describing the performance of a dichotomous test, review the relationship between sensitivity and specificity, calculate likelihood ratios to describe test performance, and conduct probability revision using the odds-LR form of Bayes. In addition to the glossary, materials include an instructor's note, videos, companion slides, an annotated bibliography, and sample exercises.

This multimedia segment, Part 1. Interpreting Information includes two videos. In the first video a practice question provides an opportunity to use information given for the prior probability and test characteristics to calculate the posterior probabilities given a positive and negative test. In the second video, the solutions are reviewed and the relationships are visually sketched out to show the influence of the sensitivity and specificity on the posterior. In addition to the videos, materials…
