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. WebAug 3, 2024 · In order for the results of parametric tests to be valid, the following four assumptions should be met: 1. Normality – Data in each group should be normally distributed. 2. Equal Variance – Data in each group should have approximately equal variance. 3. Independence – Data in each group should be randomly and independently …

WebApr 8, 2024 · Parametric tests are based on assumptions regarding the population’s underlying distribution, while nonparametric tests do not require such assumptions. Nonparametric tests are often more robust to outliers … WebFeb 26, 2010 · While nonparametric methods require no assumptions about the population probability distribution functions, they are based on some of the same assumptions as parametric methods, such as randomness and independence of the samples.
