Parametric statistics tests
WebAug 27, 2024 · This parametric test is used to know about the dependent relationship between two variables. We can predict the value of dependent variable, based on the … WebParametric tests are those that make assumptions about the parameters of the population distribution from which the sample is drawn. This is often the assumption that the population data are normally distributed. Non-parametric tests are “distribution-free” and, as such, can be used for non-Normal variables.
