Question

Quizplus · Accepted Answer

The statement involves an interval scale of measurement because the IQ score is based on a standardized and consistent measurement scale, and the difference between scores is meaningful (e.g. a score of 100 is 5 points higher than a score of 95). However, the statement does not provide a true zero point on the scale, which is required for a ratio scale. It also does not involve categories or rankings, which are characteristic of nominal and ordinal scales.
