Normality Test

A statistical test that plots the continuous (a.k.a. variable or categorical) values of a dataset along a logarithmic scale to assess if the data conforms to a normal distribution. The Anderson-Darling (AD) test is often used with this to measure probability (reflected as a P-value).
