What do false positives and false negatives mean in an alert system?
Question: Answer in one to three sentences. Explain what a false positive and a false negative mean for a system that decides whether to trigger an alert.
Sample answer: A false positive is an alert that sounds when no real event happened. A false negative is a real event that occurs, but the system fails to trigger the alert.
Key points:
- False positive: alert triggered without the event.
- False negative: event occurs but no alert is triggered.
Rubric: The answer must correctly define a false positive as an unnecessary alert and a false negative as a missed alert when the event really occurred.
