What is a nonparametric test?
12/06/2022 | by Patrick Fischer, M.Sc., Founder & Data Scientist: FDS
A nonparametric test is a statistical test that does not require any assumptions about the distribution of the data. They are particularly useful when you have data that is not normally distributed or when you do not have information about the distribution available. Nonparametric tests tend to be less powerful than parametric tests, but in many cases they can be used to test the same hypotheses.
