Question

Quizplus · Accepted Answer

This statement is false. Parametric tests are generally more powerful than nonparametric tests when the assumptions of parametric tests are met. Nonparametric tests have less strict assumptions and can be used when the assumptions of parametric tests are violated, but they may have less power to detect differences between groups.
