Web6 de mar. de 2024 · 1. It is symmetric. A normal distribution comes with a perfectly symmetrical shape. This means that the distribution curve can be divided in the middle to produce two equal halves. The symmetric shape occurs when one-half of the observations fall on each side of the curve. 2. The mean, median, and mode are equal. 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.
