What’s A Normality Test?
AKA Anderson Darling-Test For Normality
The Normality Test is a statistical test that determines whether or not a data set is normally distributed. A normal distribution is often referred to as a “Bell Curve.” Whether a distribution is normal or not determines which tests or functions can be used with a particular data set.
