- Nonparametric tests are alsoed distribution-free tests because they don 'tume that your data follow a specific distribution. You may have heard that you should use nonparametric tests when your data don 't meet theumptions of the parametric test, especially theumption about normally distributed data..A statistic estimates a parameter. Parametric statistical procedures rely onumptions about the shape of the distribution i.e.,ume a normal distribution in the underlying population and about the form or parameters i.e., means and standard deviations of theumed distribution..A potential source of confusion in working out what statistics to use inysing data is whether your data allows for parametric or non-parametric statistics..
