In statistics, the 68-95-99.7 rule, or three-sigma rule, or empirical rule, states that for a normal distribution, almost all values lie within 3 standard deviations of the mean. About 68% of the values lie within 1 standard deviation of the mean (or between the mean minus 1 times the standard deviation, and the mean plus 1 times the standard deviation). In statistical notation, this is represented as: μ ± σ.

  • In statistics, the 68-95-99.7 rule, or three-sigma rule, or empirical rule, states that for a normal distribution, almost all values lie within 3 standard deviations of the mean. About 68% of the values lie within 1 standard deviation of the mean (or between the mean minus 1 times the standard deviation, and the mean plus 1 times the standard deviation). In statistical notation, this is represented as: μ ± σ. About 95% of the values lie within 2 standard deviations of the mean (or between the mean minus 2 times the standard deviation, and the mean plus 2 times the standard deviation). The statistical notation for this is: μ ± 2σ. Almost all (99.7%) of the values lie within 3 standard deviations of the mean (or between the mean minus 3 times the standard deviation and the mean plus 3 times the standard deviation). Statisticians use the following notation to represent this: μ ± 3σ.
