Quantitative data are described as which of the following?

• A. Measurable data that can be manipulated via numerical analysis
• B. Descriptive data
• C. Qualitative categories
• D. Graphical representations

Answer: (A)

Quantitative data are numerical measurements that can be analyzed mathematically. They come from measuring or counting with units (like speed in km/h, crash counts, or time in seconds) and can be manipulated through arithmetic and statistical methods. This numeric nature lets you quantify how big or small something is and compare values across cases. Descriptive or qualitative data describe attributes or categories and aren’t expressed as numbers, while graphical representations are ways to present data rather than the data type itself.
