What is the difference between qualitative and quantitative data in decision-making?

• A. Qualitative is descriptive; quantitative is numeric and measurable.
• B. Qualitative uses numbers; quantitative uses descriptions.
• C. Qualitative data is always more accurate than quantitative data.
• D. Quantitative data cannot be used for forecasting.

Answer: (A)

Qualitative data describes qualities using words, descriptions, or categories, and it provides depth, context, and meaning behind phenomena. Quantitative data, by contrast, uses numbers to quantify those phenomena—counts, measurements, and scores that can be measured, compared, and analyzed statistically. In decision-making, qualitative insights help you understand why things happen and what people think, while quantitative data shows how much or how often, enabling comparisons and forecasting. So, the statement that qualitative data is descriptive and quantitative data is numeric and measurable captures the essential distinction. The other options miss this fundamental difference: numbers belong to quantitative data; accuracy isn’t inherently tied to qualitative vs. quantitative alone; and forecasting often relies on quantitative data.
