Question

Quizplus · Accepted Answer

Ratio variables have a true zero point, meaning that a value of zero represents an absence of the attribute being measured. Interval variables, on the other hand, do not have a true zero point as zero represents simply another point on the scale. Choices A and D are incorrect, as both interval and ratio variables have values that can be ordered.
