Normal Distribution - Definition, Formula, Examples

WebA non-normal distribution is any distribution of any kind other than normal. Most commonly in practice we find distributions are non-normal because they have a skew (a longer tail on the right or left side), though double-humped distributions and so on are also possible. Length of stay data is a great example: most patients will leave the ... WebThe standard deviation is 0.15m, so: 0.45m / 0.15m = 3 standard deviations. So to convert a value to a Standard Score ("z-score"): first subtract the mean, then divide by the Standard Deviation. And doing that is called "Standardizing": We can take any Normal Distribution and convert it to The Standard Normal Distribution.
