False positives and false negatives
False positives and negatives are words related with practical testing. When performing a practical test, there is the possibility that the result of the test does not show the real situation.
In a test, a false positive is when a test result shows that a condition is present but it is not. A false negative is when a test result shows a condition is not present when in fact it is present.
