The Empirical Rule, also known as the 68-95-99.7 Rule, is a guideline that applies to distributions that are approximately normal. It states that approximately 68% of observations fall within one standard deviation of the mean, 95% fall within two standard deviations of the mean, and 99.7% fall within three standard deviations of the mean. Therefore, the Empirical Rule can only be used when assessing a distribution that is approximately normal.
