Empirical Rule (also known as the 68-95-99.7 Rule)
In a Normal Distribution with mean μ and standard deviation σ:
- Approximately 68% of the observations fall within σ of the mean μ.
- Approximately 95% of the observations fall within 2σ of the mean μ.
- Approximately 99.7% of the observations fall within 3σ of the mean μ.
This result is known as the empirical rule.
