Which statement about data types is true?

• A. Qualitative data involve descriptions and attributes.
• B. Quantitative data involve descriptions.
• C. All data are qualitative.
• D. Data are always numeric.

Answer: (A)

Data types are split into qualitative (descriptive) and quantitative (numeric) data. Qualitative data describe qualities or categories—things you can label or describe with words, such as colors, textures, or types of objects. They answer “what kind” questions rather than “how many.” Quantitative data, on the other hand, are measured and expressed as numbers—counts or measurements like height, temperature, or test scores. So the statement that qualitative data involve descriptions and attributes is correct because it captures the essence of qualitative data being non-numeric and descriptive. The other ideas don’t fit: data aren’t all descriptions (some are numeric), and data aren’t always numeric (there are many qualitative examples).
