The difference between an interval level variable and a ratio level variable is ______.
A) interval level variables have equal distance along a numeric continuum
B) interval level variables have a true zero point
C) ratio level variables have a true zero point
D) ratio level variables do not allow for a greater number of comparisons

Question

Quizplus · Accepted Answer

Ratio level variables have a true zero point, meaning that the value of zero represents the complete absence of the measured quantity. This allows for meaningful ratios to be calculated, such as "twice as much" or "half as much," which is not possible with interval level variables. Therefore, option B and D are incorrect. While option A is a characteristic of interval level variables, it is not the defining difference between interval and ratio level variables.
