Step 1

Reason for correct answers:

In general nonparametric statistic procedures are inferential procedures and they are not based on any specific distribution or parameter of the data. These procedures are called as distribution free procedures.

Step 2

Therefore, the nonparametric procedures can be applied to categorical data. Thus, correct option is A) Categorical data.

Reason for incorrect answers:

Here, the nonparametric procedures are distribution free procedures. Therefore, options B, C and D are incorrect.
