- 4. Ratio scale
A1, 2 and 3 only
B2, 3 and 4 only ✓ Correct
C2 only
D1 and 2 only
Correct answer: (B) 2, 3 and 4 only — Ranking is allowed by the ordinal, interval and ratio scales, so the answer is 2, 3 and 4.
Explanation
★Ranking is allowed by the ordinal, interval and ratio scales, so the answer is 2, 3 and 4.
★A scale allows ranking if its values can be placed in order.
★The ordinal scale directly ranks observations in order.
★The interval scale has ordered values with equal gaps, so it also ranks.
★The ratio scale has order plus a true zero, so it ranks as well.
★The nominal scale only labels categories without order, so statement 1 is excluded.
