![]() Where \(Z\) is the value on the standard normal distribution, \(X\) is the value on the original distribution, \(\mu\) is the mean of the original distribution, and \(\sigma\) is the standard deviation of the original distribution. Example: Relative frequency distribution. The sample size is the sum of the frequencies. \): An example from the appletĪ value from any normal distribution can be transformed into its corresponding value on a standard normal distribution using the following formula: To calculate the relative frequencies, divide each frequency by the sample size.
