Quizplus · Accepted Answer

The ability to quantify the difference between Tom's and Bill's scores (by stating it is four points higher) indicates the use of a scale that not only ranks individuals but also allows for the measurement of the exact difference between them. This characteristic is present in both interval and ratio scales. Nominal scales categorize without any order, and ordinal scales rank but do not specify the magnitude of difference between ranks.
