Quizplus · Accepted Answer

Nonparametric tests are used when the distributional assumptions of the corresponding parametric test are not met. Nonparametric tests do not rely on assumptions about the shape or size of the population distribution, making them a more flexible alternative. Parametric tests assume that the data is drawn from a particular distribution, typically a normal distribution. If this assumption is violated, the results of the parametric test may not be accurate.
