WebJan 27, 2024 · A commonly used approach is the 3 Sigma rule. If your measurement is more than three standard deviations away from your average, this measurement is considered an anomaly. But as illustrated in the image above, you still have a 0.1% probability that your prediction was incorrect; and that the measurement was, in fact, an expected value.
