Step 1
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.
Here, the nonparametric procedures are distribution free procedures. Therefore, options B, C and D are incorrect.
