Quizplus · Accepted Answer

The number of children in a family is a quantitative variable that can be measured at the interval-ratio level because it has equal intervals between values and a true zero point (i.e., having zero children). The other options are either categorical variables (A) or subjective traits that cannot be quantified on a numerical scale (C, D).
