WebThese numerical values (68 - 95 - 99.7) come from the cumulative distribution function (CDF) of the normal distribution. For example, F (2) = 0.9772, or Pr (x ≤ μ + 2σ) = 0.9772. Note that this is not a symmetrical interval – this is merely the probability that an observation is less than μ + 2σ.

Web6.2 Characteristics of the Normal Distribution There are eight key characteristics that define a normal distribution. 1. The normal distribution is mathematically defined: An exact normal distribution is defined by a mathematical formula—however, rarely (if ever) do data fall exactly within the limits . of the formula. 2. WebNormal distribution, despite its simple name and relatively easy-to-understand definition, is actually a very interesting concept. Any time you add together a large amount of random variables, even if those variables are from different distributions, if you get enough samples you'll find that the sum of the variables tends to be normally distributed.
