What are false positives and false negatives and why are they important when investigating an outbreak?

False Positives are where you say something is false even though it is true.
False Negatives are where you say something is true even though it is false.

False Positives occur when there is enough random variation in the population to assume that something has changed, on the other hand False Negatives occur when the change is too small to think much has changed.
