Quizplus · Accepted Answer

Interval scales have equal intervals between the scale points and can measure absolute differences between them. For example, the difference between 50 and 60 on a temperature scale is the same as the difference between 80 and 90. This makes it possible to perform arithmetic operations like addition and subtraction on the scale points.
