Abstract
This presentation summarizes an investigation into series of tests that indicate whether a subject is positive or negative for some condition. The research explores facts related to the sensitivity and specificity of tests, using this information in conjunction with Bayes’ Theorem to determine the probability of a subject being truly positive given any combination of test results. This is used to assess the effectiveness of certain testing procedures and find the relationship between positive and negative tests that is required to reach a particular threshold of certainty that a subject is truly its diagnosed condition.
