Quizplus · Accepted Answer

Weight is a continuous variable that has a true zero point (i.e. there is a meaningful definition of "no weight"), making it an example of a ratio scale. Nominal scales involve categories without any inherent order or ranking, ordinal scales involve categories with a meaningful order or ranking but no fixed measurement units, and interval scales involve categories with equal distance between them but no true zero point.
