Which level of measurement involves ranking values but with unequal intervals between them?

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

Answer: (C)

Ranking values with unequal intervals describes ordinal data. In this level, you can say one value is higher or lower than another, so there is an order, but the distance between successive ranks isn’t assumed to be equal. That means you can state that A ranks above B, but you can’t quantify exactly how much bigger the difference is. This contrasts with interval data, where differences between values are meaningful and equal (like temperature in Celsius, where 10 degrees and 20 degrees represent the same interval), and ratio data, which also has a true zero and equal intervals (like weight or height). Nominal data, meanwhile, has categories with no inherent order.
