Question

Quizplus · Accepted Answer

Parametric methods assume a specific distribution or form for the data, while nonparametric methods make no such assumptions or only minimal assumptions. If the underlying distribution of the data is known and the assumptions of the parametric method hold, then parametric methods can be more powerful than nonparametric methods. However, if these assumptions are not met, nonparametric methods may be more powerful. Therefore, the superiority of one approach over the other depends on the specific characteristics of the data and the research question being investigated. Hence, sometimes parametric methods can be more powerful than their nonparametric counterparts.
