B) nonparametric techniques
C) parametric techniques
D) distribution-free techniques and nonparametric techniques
E) none of these

Quizplus · Accepted Answer

Parametric techniques assume that the data follows a specific distribution, usually the normal distribution. Nonparametric techniques do not require any specific distribution assumption, and distribution-free techniques are a subset of nonparametric techniques that do not make any assumptions about the underlying distribution. Therefore, the correct answer is C.
