Nonparametric tests CAN be used when data is expressed in terms of ranks, its one of the features, right?

 

[mcf]

I believe that is correct.
SO if the answer D?

 

[DArtagnan]

Correct Answer: C.
Nonparametric tests may certainly be used when data is expressed in terms of ranks.

Wow… i’m having some serious “least likely” issues on questions today…

Either way, wouldnt D or A cancel each other out. So it would just be between B & C…
