The example 'Class standing' illustrates which measurement level?

• A. Ordinal
• B. Nominal
• C. Interval
• D. Ratio

Answer: (A)

The main idea is that class standing is a ranked category, which makes it ordinal data. You can place students in a meaningful order—from freshman to sophomore to junior to senior—so there is a clear sequence. But the differences between adjacent levels aren’t necessarily equal, and there isn’t a true zero point to indicate “no standing.” Because of those aspects, it isn’t interval data (where equal distances between points matter) or ratio data (which would require a true zero). It also isn’t nominal data, since nominal categories have no inherent order. So the best description for class standing is ordinal.
