Quizplus · Accepted Answer

Nonparametric statistics do not make assumptions about the distribution from which the samples are taken, so option A is correct. Option II is also correct because parameters of the distribution, such as mean and variance, do not directly relate to the parameters of the sample. Option III is not correct because nonparametric methods can be used for comparing distributions with common parameters (e.g. comparing two populations with the same median).
