Standard distribution graph
WebbThe standard deviation determines the spread of the distribution. For example, in the following graph of a normal distribution, approximately, 68% of observations are within +/- 1 standard deviation of the mean; 95% are within +/- 2 standards deviations of the mean (as shown by the shaded area); and 99.7% are within +/- 3 standard deviations of the … WebbSpecifically, the z-scores follow the standard normal distribution, which has a mean of 0 and a standard deviation of 1. However, skewed data will produce z-scores that are similarly skewed. In this post, I include graphs of z-scores using the standard normal distribution because they bring the concepts to life.
