What is another word for nonparametric?
Pronunciation: [nˌɒnpˌaɹəmˈɛtɹɪk] (IPA) 
Nonparametric is a term used in statistics which indicates that certain assumptions about the population being studied do not need to be made. There are several synonyms for the term nonparametric, including distribution-free, assumption-free, data-driven, and model-free. These synonyms emphasize the core idea behind nonparametric statistics, which is that the data itself provides the information needed to draw conclusions, rather than relying on preconceived notions about the population. Nonparametric methods are often used when the data does not meet the assumptions of normality or homogeneity of variance required for parametric analysis, making them an important tool in many fields of research.
