drdoomPut another way: Of all the people who are disease-free, how many (of those people) did you catch? In this case, there are 100 people who are disease-free; our test labeled 95 of those people as “disease-free”, but our test also called 5 of those people “positive”; so our test is good (sort of) but not that good.+12019-06-27T21:51:22Z
drdoomAlso note how specificity only answers questions about people WITHOUT THE DISEASE; it only “deals with” people who are disease-free. (Sensitivity is the opposite: it is a formula which only deals with people WITH THE DISEASE. I think understanding that is better than coming up with some crazy Snout-Spout-Spin mnemonic, which I never remember anyway.)+2019-06-27T21:57:18Z
