How much is one sigma
WebSigma is governed by the manufacturing process used to create the part as described earlier. Let's also consider the following properties of the normal distribution: 68.3% of parts fall within +/- one sigma from the mean. 95.5% of parts fall within +/- two sigma from the mean. 99.7% of parts fall within +/- three sigma from the mean. Suppose that the entire population of interest is eight students in a particular class. For a finite set of numbers, the population standard deviation is found by taking the square root of the average of the squared deviations of the values subtracted from their average value. The marks of a class of eight students (that is, a statistical population) are the following eight values: These eight data points have the mean (average) of 5:
