Which type of data is measured?

• A. Qualitative data
• B. Quantitative data
• C. Ordinal data
• D. Nominal data

Answer: (B)

Measured data are numeric values obtained by counting or measuring something with a unit. Because they carry numbers and units, these values can be used in arithmetic and statistics, which is what makes them quantitative data.

Qualitative data describe qualities or categories and aren’t inherently numeric. Among the qualitative types, nominal data are categories with no natural order, and ordinal data have a rank order but the intervals between ranks aren’t assumed to be equal. Since the question uses the term “measured,” the emphasis is on data that are numeric measurements, i.e., quantitative data.
