Explain the concept of non-parametric test

WebReview Questions 1. Explain the difference between parametric and non-parametric statistical tests. Parametric tests make certain assumptions about the population the research sample is representing (e.g., assumption that the measured variable is normally distributed in the population). In contrast, non-parametric tests do not require … 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.
