Quizplus · Accepted Answer

The proportion of the total area under a normal curve between two z-scores is a relative frequency. This is because it represents the proportion of scores within that range relative to the total number of scores. The other choices are not accurate because numeric magnitude refers to the value of individual scores, variability refers to the spread of scores, and frequency refers to the number of times a score occurs in a distribution.
