Sigmas on normal curve
WebIt’s quite ironic really, sometimes, a normal distribution isn’t exactly the normal thing in the real world. Sure, with enough data we may end up leveraging the law of large numbers and tend to “normal” — but in some real-life scenarios (such as in finance), we may not have much data and the distribution is likely skewed.

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 … See more 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).
