Data measured on an ordinal scale have equal intervals between their ranks.

Question

Quizplus · Accepted Answer

Data on an ordinal scale have a ranking order, but the intervals between each rank are not necessarily the same. For example, if we rate restaurants on a scale of 1-5 stars, the difference in quality between a 2-star restaurant and a 3-star restaurant may not be the same as the difference between a 4-star restaurant and a 5-star restaurant. Therefore, the intervals are not equal.
