Question of the day

Which statement best describes the false positive rate in a screening test with poor specificity?

The main idea is that the false positive rate is the fraction of people who do not have the disease but test positive. It is equal to 1 minus the test’s specificity. In a screening test with poor specificity, many non-diseased individuals will receive positive results, so the false positive rate is high. The statement that best captures this is that the false positive rate is the proportion of non-diseased individuals incorrectly identified as diseased. The other descriptions correspond to true positives (diseased correctly labeled as diseased) or false negatives (diseased labeled as non-diseased), which are not about false positives.
