Determining the class standing (1st, 2nd, and so on) for the graduating seniors would involve measurement on a(n) ____ scale of measurement.

Determining the class standing (1st, 2nd, and so on) for the graduating seniors would involve measurement on a(n) ____ scale of measurement.

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

Answer: (B)

Ranking graduating seniors by class standing is about order, not precise differences. When you say someone is first, second, or third, you’re expressing a position relative to others—the person is ahead of the rest, but you’re not specifying how far ahead or by how much their performance differs. That ordering is what defines an ordinal scale: you can say who is ahead or behind, but the intervals between ranks aren’t guaranteed to be equal. There isn’t a true zero point to indicate “none” of standing, and you can’t meaningfully form ratios between ranks. In contrast, a nominal scale would only label categories with no inherent order; an interval scale would require equal distances between points (like temperature in Celsius), and a ratio scale would require a true zero and meaningful ratios (like height or score with a true zero). Since class standing conveys order without equal intervals or a true zero, ordinal is the appropriate type.
