Quizplus · Accepted Answer

Parametric tests assume that the data follows a specific probability distribution, such as a normal distribution, and require certain parameters to be estimated from the data. Examples include the z-, t-, and F-tests. Nonparametric tests, on the other hand, do not assume a specific distribution and are often used for data that does not meet the assumptions of parametric tests. Distribution-free statistics are a type of nonparametric test that do not make any assumptions about the underlying probability distribution. The sign test is a specific nonparametric test used for comparing two dependent samples.
