Quizplus · Accepted Answer

The main difference between a ratio scale of measurement and an interval scale of measurement is that a ratio scale has a true zero point, meaning that a value of zero represents the complete absence of the measured quantity. On the other hand, an interval scale does not have a true zero point, and a zero value only represents a point on the scale.
