WebParametric and nonparametric statistics Statistics - parametric and nonparametric Parametric statistics are based on assumptions about the distribution of population from which the sample was taken. Nonparametric statistics are not based on assumptions, that is, the data can be collected from a sample that does not follow a specific distribution. WebWhat is a Non Parametric Test? A non parametric test (sometimes called a distribution free test) does not assume anything about the underlying distribution (for example, that the data comes from a normal distribution).That’s compared to parametric test, which makes assumptions about a population’s parameters (for example, the mean or standard …
