In general, a primary reason for choosing a nonparametric procedure over a parametric one is:
A) nonparametric procedures do not require parameters that limit the scope of an experiment.
B) nonparametric procedures generally require fewer assumptions than parametric procedures.
C) parametric procedures make inferences on parameters, whereas nonparametric procedures do not.
D) the assumption of normality, which most parametric procedures require, is rarely valid.

Nonparametric procedures generally require fewer assumptions than parametric procedures, which makes them a better choice when the assumptions of parametric procedures are not met or when there is limited knowledge about the underlying population distribution. Nonparametric procedures are also more robust to outliers and non-normal data.
