Data that are numerical measurements like height or weight are called

• A. Qualitative data
• B. Discrete numerical data
• C. Secondary data
• D. Quantitative data

Answer: (D)

When data are numerical measurements like height or weight, they describe amounts and are expressed as numbers, not categories. That makes them quantitative data. Qualitative data describe qualities or categories (like color or type) and aren’t numeric. Discrete numerical data are counts that can only be whole numbers (like the number of siblings), whereas height and weight aren’t restricted to integers and can take a continuum of values, so they’re continuous within numerical measurements. Secondary data refers to data collected by someone else or for another purpose, not to the type of data. So the term that fits best is quantitative data.
