What is quantitative data?

• A. Qualitative data
• B. Data that describes opinions
• C. Enables measurement
• D. Qualitative observations

Answer: (C)

Quantitative data are numbers that quantify something and can be measured with units. This enables measurement, arithmetic, and statistical analysis—so you can compare values, spot trends, and quantify change. The other descriptions refer to data that are descriptive or opinion-based and not readily numeric, so they don’t support the same kind of numeric analysis. Examples include height in centimeters or sales figures, which illustrate measurements that quantitative data captures.
