The simplest case of a normal distribution is known as the standard normal distribution or unit normal distribution. This is a special case when and , and it is described by this probability density function (or density): The variable has a mean of 0 and a variance and standard deviation of 1. The density has its peak at and inflection points at and . WebThe Empirical Rule for any normal distribution: Approximately 68% of the data is within one standard deviation of the mean. Approximately 95% of the data is within two standard deviations of the mean. Approximately 99.7% of the data is within three standard deviations of the mean. Figure 6.2. 4: Empirical Rule
WebInstead, graph these distributions using normal probability Q-Q plots, which are also known as normal plots. These plots are simple to use. All you need to do is visually assess whether the data points follow the straight line. If the points track the straight line, your data follow the normal distribution. It’s very straightforward!
