Quizplus · Accepted Answer

The categories could also be rank ordered as (1) underweight, (2) normal, and (3) overweight.
"Categorical" is not a level of measurement.
Interval cannot be used because there are no numerical divisions.
This could not be ratio data because there is no True zero represented in the categories.
