A)assumptions of parametric tests are not met
B)population distribution is normal
C)variances of scores are equal in the populations sampled
D)dependent variable achieves interval measurement

Question

Quizplus · Accepted Answer

Nonparametric tests should be used when the assumptions of parametric tests are not met, such as when the sample size is small or the data is not normally distributed. Nonparametric tests do not require the same assumptions as parametric tests and are therefore more appropriate in these situations. Choice B is incorrect because nonparametric tests are not dependent on the normality of the population distribution. Choice C is incorrect because equal variances are an assumption of parametric tests, not nonparametric tests. Choice D is incorrect because achieving interval measurement is a characteristic of the dependent variable, not a consideration for choosing between parametric and nonparametric tests.
