Which of the following statements about nonparametric methods is correct?
A)Nonparametric methods are only used in cases where parametric tests such as t or F do not exist.
B)Nonparametric tests should always be used when one is available because they are easier to apply then their parametric counterparts.
C)Nonparametric tests are useful alternatives to parametric tests such as t or F when certain assumptions required by parametric tests are violated.
D)Nonparametric tests are only used if the data come from independent samples.

Question

Quizplus · Accepted Answer

Nonparametric tests are useful when the assumptions required by parametric tests are not met, such as when the data are not normally distributed, or when the sample size is small. Nonparametric tests can be applied to both independent and dependent samples. However, it is not always true that nonparametric tests are easier to apply than their parametric counterparts. The choice between using parametric or nonparametric tests depends on the specific research question and the characteristics of the data.
