Quizplus · Accepted Answer

The ratio scale allows for the comparison of the magnitude of scores and the use of mathematical operations, such as multiplication and division, which is necessary for the statement "five times as large." Nominal scales only allow for the classification of variables, ordinal scales allow for ranking, and interval scales allow for comparison of intervals but not multiplication/division operations.
