Question

Quizplus · Accepted Answer

The grades do have an order or ranking, with A being the highest, B being the second highest, and C being the lowest. However, we cannot assume that the difference between an A and a B is the same as the difference between a B and a C, so it cannot be interval. Additionally, we cannot perform mathematical operations on the grades, such as taking an average, so it cannot be ratio. Lastly, nominal data are categories that do not have an inherent order, so it cannot be nominal. Therefore, ordinal is the best choice.
