Question

in a study, the data you collect is weight in pounds. what is the level of measurement?
nominal
ordinal
interval
ratio

Explanation:

Ratio level measurement has a true zero point, allows meaningful comparisons of magnitudes, and supports all arithmetic operations including division. Weight in pounds has a true zero (0 pounds means no weight), and we can meaningfully say 100 pounds is twice 50 pounds, which fits the ratio level criteria. Nominal data is for categorization without order, ordinal has ordered categories but no consistent interval, and interval has consistent intervals but no true zero.

Answer:

ratio
