Quizplus · Accepted Answer

Ratio is the strongest level of measurement as it has all the properties of interval scale along with a true zero point, which allows the comparison of magnitudes, addition, and multiplication of data. Nominal and ordinal scales have limited mathematical properties and cannot be used for arithmetic operations. Interval scale has only a fixed unit of measurement but lacks a true zero point.
