Question

Quizplus · Accepted Answer

The ratio scale is the most complex of the primary scales of measurement because it includes all the characteristics of the other scales (nominal, ordinal, and interval) while also including a true zero point, which allows for the comparison of ratios between values. This means that not only can we identify differences between values, we can also understand how much larger or smaller one value is compared to another. For example, if we are measuring weight, we can say that a person who weighs 100 pounds is twice as heavy as a person who weighs 50 pounds. This level of measurement is considered the most informative and precise.
