Nonparametric Methods and SPC for Excel
Click here to see a video on the four nonparametric methods in SPC for Excel
SPC for Excel contains four nonparametric methods. Many statistical methods are based on the assumption of normally distributed data. This assumption is often not valid or the sample size is too small to determine if the data are normally distributed. Parametric tests do not require the data to be normally distributed. These tests are sometimes called distribution-free methods. The output for one of the methods (Mann-Whitney) is shown above.
