The Empirical Rule When a population has a histogram that is approximately bell-shaped, then Approximately 68% of the data will be within one standard deviation of the mean. In other words, approximately 68% of the data will be between µ − σ and µ + σ. Approximately 95% of the data will be within two standard deviations of the mean. In other words, approximately 95% of the data will be between µ − 2σ and µ + 2σ....William Navidi, Barry Monk Elementary STATISTICS Second Edition
