In measurement scales, a score of 0 on a ratio scale indicates:

• A. A true zero point
• B. It cannot occur in ratio scales
• C. It indicates a minimal score
• D. It indicates a complete absence of the attribute

Answer: (D)

Zero on a ratio scale is an absolute zero, meaning there is a complete absence of the attribute being measured. Because ratio scales have this true zero, the zero score conveys that nothing of the quantity is present, which also lets you interpret ratios meaningfully (for example, twice as much). That’s why this option—representing complete absence of the attribute—fits best. The other statements don’t align with how ratio scales work: zero does occur on ratio scales, it isn’t merely a minimal score, and while a ratio scale has a true zero, the key interpretation is the complete absence of the attribute.
