In statistics, the 68–95–99.7 rule, also known as the empirical rule, is a shorthand used to remember the percentage of values that lie within an interval estimate in a normal distribution: 68%, 95%, and 99.7% of the values lie within one, two, and three standard deviations of the mean, respectively. In … Visa mer These numerical values "68%, 95%, 99.7%" come from the cumulative distribution function of the normal distribution. The prediction interval for any standard score z corresponds numerically to (1−(1−Φμ,σ (z))·2). Visa mer The "68–95–99.7 rule" is often used to quickly get a rough probability estimate of something, given its standard deviation, if the population is assumed to be normal. It is also used as a simple test for outliers if the population is assumed normal, and as a Visa mer • p-value • Six Sigma#Sigma levels • Standard score Visa mer • "The Normal Distribution" by Balasubramanian Narasimhan • "Calculate percentage proportion within x sigmas at WolframAlpha Visa mer WebbThe process standard deviation is .15, and the process control is set at plus or minus one standard deviation.
