Question

Quizplus · Accepted Answer

The key difference between ratio and interval scales is the presence of an absolute zero point. Ratio scales have an absolute zero, meaning that a score of zero indicates the absence of the measured characteristic. Interval scales do not have an absolute zero, meaning that a score of zero still indicates the presence of the characteristic but at the lowest possible level. The other choices (A, C, and D) do not differentiate between ratio and interval scales.
