Which is a quantitative data example?

• A. Interview responses
• B. DMFT scores
• C. Observed behaviors
• D. Satisfaction with care

Answer: (B)

Quantitative data are numerical measurements that can be counted and analyzed statistically. DMFT scores provide a numeric index—the count of decayed, missing, and filled teeth—resulting in precise values that allow comparisons across individuals or groups and enable mathematical analysis. This makes them a clear example of quantitative data. In contrast, interview responses are expressed as words and ideas (qualitative data), observed behaviors are typically described in descriptive terms (qualitative), and satisfaction with care is usually captured with subjective ratings on a scale (often treated as ordinal data). Thus DMFT scores best illustrate quantitative data.
