When recording height and weight in MDS, how should measurements be rounded?

• A. Height to the nearest inch; weight to the nearest pound
• B. Height to the nearest foot; weight to the nearest kilogram
• C. Height to the nearest half inch; weight to the nearest 5 pounds
• D. No rounding

Answer: (A)

Height should be recorded to the nearest inch and weight to the nearest pound because MDS uses imperial units and standardizes entries to whole units. Heights are typically measured with a stadiometer that provides inches, so rounding to the nearest inch matches the tool’s output and keeps data consistent across facilities. Scales report weight in pounds, so rounding to the nearest pound maintains simplicity and comparability. Rounding height to the nearest foot or half inch would add unnecessary variation, and rounding weight in larger increments or not rounding at all would reduce precision and hinder comparability.
