Companion Slides: Using Test Information II
2022
These companion slides accompany the videos included in the teaching pack on Using Test Information II, in which students are introduced to tests with continuous or categorical results, and calculate the sensitivity and specificity conditional on different ‘cutoff points’ or 'positivity criterion'. They are introduced to ROC curves and explore the implications of operating at different parts of the curve for any single test. They calculate the optimal positivity criterion given information on the prior, the test performance, and the relative consequences of true positives, false negatives, and false positives. In addition to the companion slides, materials include an instructor's note, videos, a glossary, an annotated bibliography, and sample exercises.
Companion slides for Part 1. Introducing Continuous Test Results videos:
- Video 1.1. Continuous test results (~11 min)

Companion slides for Part 2. Optimal Positivity Criterion, Iron Deficiency videos:
- Video 2.1. Iron deficiency case – 1 (~10 min)

This teaching pack was developed by Sue J. Goldie at the Center for Health Decision Science, Harvard T.H. Chan School of Public Health. The multimedia components were developed as part of a series of pilots in the CHDS Media Hub, led by Jake Waxman, where media-based pedagogy experiments contribute to new ways of thinking about short form content.
