Which of the following describes a quantitative field?

• A. Numeric measurements.
• B. Location names.
• C. Text notes about observations.
• D. Categorical labels like season.

Answer: (A)

Quantitative data are numbers that represent quantities you can measure and compare. A field with numeric measurements fits this idea because its values are numbers you can perform arithmetic on—adding, averaging, calculating ranges, and applying statistics. In contrast, location names are words used as labels for places, which are qualitative. Text notes about observations are descriptive rather than numerical, also qualitative. Categorical labels like season classify data into groups without implying any numeric amount, so they’re not quantitative. Therefore, numeric measurements best describe a quantitative field.
