Question

Quizplus · Accepted Answer

This is an example of ordinal scale of measurement because the grades can be ordered from highest to lowest, but the intervals between each grade are not necessarily equal. In other words, the distance between an A and a B is not necessarily the same as the distance between a C and a D. Therefore, it is not an interval or ratio scale of measurement. It is also not a nominal scale of measurement because the categories (grades) can be ranked in a meaningful way.
