Under this rule, 68% of the data falls within one standard deviation, 95% percent within two standard deviations, and 99.7% within three standard deviations from the mean. The Empirical Rule states that 99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean.
What is 3 standard deviations from the mean? In the empirical sciences, the so-called three-sigma rule of thumb expresses a conventional heuristic that nearly all values are taken to lie within three standard deviations of the mean, and thus it is empirically useful to treat 99.7% probability as near certainty. Also, if you need the standard deviation of a population, you should use STDEVP instead.
To get 3 sigma you need to multiply it by 3. In Excel STDEV yeilds one sample standard deviation. Subtract the product in step 4 from the mean. The three-sigma process: Calculate the mean.
