Which scale has ordered categories without equal intervals between values?

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

Answer: (B)

This question tests recognizing measurement scales by how they handle order and spacing. The best answer describes a scale with ordered categories where the gaps between adjacent values aren’t assumed to be equal. You can rank items or responses (one value is higher or lower than another), but you can’t quantify the exact difference between ranks. A typical example is a ranking or a Likert-style item (1 to 5 for agreement), where 2 is higher than 1, but the distance from 1 to 2 isn’t guaranteed to match the distance from 4 to 5. In contrast, a nominal scale has no inherent order; an interval scale has ordered values with equal intervals but no true zero; and a ratio scale has equal intervals with a meaningful zero. Therefore, ordering without guaranteed equal gaps points to the ordinal scale.
