전 국민을 코로나 진단키트로 검사하지 않는 수학적 이유 | 조건부확률

There is an ENG subtitle. Please turn on Youtube SUB] While talking to a friend about the covid-19, My friend told me this. "If we test the entire nation with a diagnostic kit, won't it be solved right away?" But the situation is more complicated than he thought. Even if it is 99% perfect accurate diagnostic kit, the error rate is significant. To make it easier to understand the reason, I made it into a video. This video talks about the sensitivity and specificity often mentioned in the news and answers why it is not a good idea to examine the entire nation. --------------------------------------- this video include the concept of true positive, true negative, false positive, false negative, type 1 error, type 2 error, and FDR with conditional probability. --------------------------------------- Some of you may be wondering how much FDR changes when infection rate, sensitivity, and specificity change. If you want to check the variables yourself, you can go into the Google sheet at the address below and download it to the drive as a file-import, or download as the Excel. ------------------------------------- Some Sources FauzIDEA, Iconfinder, Attribution 3.0 Unported (CC BY 3.0) https://www.iconfinder.com/FauzIDEA Isared Honghin, Iconfinder, Attribution 3.0 Unported (CC BY 3.0) https://www.iconfinder.com/acehonghin fukin ride, Iconfinder, Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0) BomSymbols . , Incofinder, Free for commercial use https://www.iconfinder.com/korawan_m
