Parametric tests usually have stricter requirements than nonparametric tests, and are able to make stronger inferences from the data. They can only be conducted with data that adheres to the common assumptions of statistical tests.

WebIn this lesson, we'll learn how to use what is called the Run Test to test whether the distribution functions F ( x) and G ( y) of two continuous random variables X and Y, respectively, are equal. That is, we'll use the Run Test to test the null hypothesis: H 0: F ( z) = G ( z) against any of the typical alternatives. WebThere is a wide range of statistical tests. The decision of which statistical test to use depends on the research design, the distribution of the data, and the type of variable. In general, if the data is normally distributed, parametric tests should be used. If the data is non-normal, non-parametric tests should be used. office closed for thanksgiving holiday
