Which statement best describes metric data in skeletal analysis?

• A. Qualitative traits scored as present/absent
• B. Quantitative measurements
• C. Subjective impressions
• D. Field notes

Answer: (B)

Metric data are numerical measurements that quantify specific dimensions of bones, such as bone length, width, and angles. These values are objective and can be compared statistically across individuals or groups, making them essential for osteometry and stature or ancestry estimates. Standardized tools like osteometric boards and calipers help ensure consistency and allow calculation of measurement error, which is important for scientific rigor.

This is why the statement describing metric data as quantitative measurements is the best fit. Qualitative traits scored as present/absent are categorical, not numerical. Subjective impressions lack standardized numeric values, and field notes, while informative, are not the measured data themselves.
