Quizplus · Accepted Answer

Ratio scale is the most appropriate choice as it allows for meaningful comparisons of the differences in numeric values, such as height and weight, between groups. The ratio scale has a true zero point, which allows for the calculation of ratios such as body mass index or weight-to-height ratios. Nominal and ordinal scales do not allow for meaningful numeric comparisons, and interval scales do not have true zero points.
