In a disease test, which mistake is worse?
Short answer. A false negative.
Why?
A sick person is missed and goes untreated.
Disease test mistakes
| Mistake | Result |
|---|---|
| False Pos. | extra test |
| False Neg. | no treatment |
Remember
| Missed case: dangerous |
| Ask which costs more |
Two wrong answers. Is one more dangerous? Yes, in a disease test. A false positive only means an extra test. A false negative sends a sick person home untreated. A missed case is dangerous. Always ask which mistake costs more.
