Non Parametric Statistics

Statistics dealing with data that does not come from a known probability distribution. Very useful as the methods can be used in Six Sigma for any type of data. However, if used for parametric data, non parametric methods will give higher p values as less information (no knowledge of data distribution) is used in the hypothesis test
