Question

Quizplus · Accepted Answer

Nominal scales are used to categorize and label observations. They do not have any inherent numerical value or order. Therefore, in classification purposes, nominal scaled numbers serve as labels for classes or categories. Ordinal scales have a ranking order but do not have known or equal intervals between categories. Intervals are present in interval scales, but there is no true zero point. Ratio scales have all the properties of interval scales, with the addition of a true zero point, making them the most informative scale. However, ratio scales are not typically used for classification purposes.
