Hello this question is incomplete. The complete question would be:

"A researchers assigns the following number scale to high school classes:

quantitative  measures.

Explanation:

A quantitative measure serves to assign a quantity value to an object or event that will be compared to the standard adopted for such a measure. In other words, we can say that this kind of measure is represented by characteristics that can be described by numbers.

We can say that the researcher, shown in the question above, used quantitative measures because he assigned a numerical scale to the characteristics he was evaluating.

i believe the answer would be 'd'.
