NONPARAMETRIC Meaning and
Definition
-
Nonparametric is a term used in statistics and data analysis to refer to a method or approach that does not rely on specific assumptions about the underlying probability distribution of the data. In nonparametric statistics, the researcher does not need to make assumptions such as normality or linearity of the dataset, allowing for more flexibility in analyzing different types of data.
A nonparametric method aims to estimate the unknown population parameter or to test hypotheses without specifying particular forms for the distribution. It focuses on ranking or ordering the data instead of relying on specific values. Nonparametric methods are particularly useful when dealing with small sample sizes, skewed or non-normal data distributions, or when the researcher has minimal prior knowledge about the population being studied.
Some common nonparametric tests include the Mann-Whitney U test, Wilcoxon signed-rank test, Kruskal-Wallis test, and Spearman's rank correlation coefficient. These tests compare sample data without making assumptions about the underlying distributions, making them robust against outliers and resistant to violations of assumptions.
In summary, nonparametric refers to statistical methods that do not rely on making assumptions about the specific distribution of the data being analyzed. These methods provide flexibility in analyzing various types of data and are particularly useful when assumptions of parametric techniques cannot be met or when minimal prior knowledge is available about the population being studied.

Etymology of NONPARAMETRIC
The word "nonparametric" originates from the combination of the Latin word "non" meaning "not" or "without", and the term "parametric", derived from the Greek word "para" meaning "beyond" or "beside", and "metron" meaning "measure". In statistics and mathematics, "parametric" refers to the use of parameters to define and describe a model or distribution, while "nonparametric" refers to methods that do not depend on specific parameter assumptions. Therefore, the term "nonparametric" signifies a statistical method or analysis that does not rely on predetermined parameters.
