Define quantitative data.

Define quantitative data.

• A. Information about the qualities or characteristics of what is being studied. They are descriptions or words.
• B. Data that describe colors and textures.
• C. Information about quantities or amounts of what is being studied. Usually expressed in numerical form.
• D. Observations made without measurement.

Answer: (C)

Quantitative data are numbers that express amounts or quantities. They let us measure how much, how many, or how big something is, and they can be used in calculations and comparisons. For example, a height in centimeters, a test score, or the amount of rainfall are quantitative because each value is a numerical measurement. Qualitative data, by contrast, describe qualities or characteristics in words—like color, texture, or descriptions of a person or object. Observations without measurement also fall into this category, since they don’t rely on numbers. So the option that explains information about quantities or amounts, usually in numerical form, best fits quantitative data.
