WebThe empirical rule, also called the 68-95-99.7 rule or the three-sigma rule, is a statistical rule for the normal distribution which describes where the data falls within three standard deviations of the mean. Mathematically, the rule can be written as follows: P ( μ − σ ≤ x ≤ μ + σ) ≈ 0.683. P ( μ − 2 σ ≤ x ≤ μ + 2 σ) ≈ ...
