In evaluation, how are qualitative and quantitative data different?

• A. Quantitative data are numerical and allow statistical analysis; qualitative data are descriptive and explore context and meaning.
• B. Quantitative data are descriptive.
• C. Qualitative data are numerical and allow statistical analysis.
• D. Both mean the same.

Answer: (A)

The main idea tested is how data types differ in evaluation and how they’re used to learn from a study. Quantitative data use numbers to quantify variables, enabling statistical analysis, comparisons, and estimates of magnitude. Qualitative data are descriptive and narrative, capturing context, meanings, experiences, and reasons behind actions. Because of these differences, quantitative data provide breadth and measurable patterns, while qualitative data provide depth and understanding of the how and why behind those patterns. This aligns with the description that quantitative data are numerical and allow statistical analysis, whereas qualitative data are descriptive and explore context and meaning. Describing quantitative data as merely descriptive or describing qualitative data as numerical would miss the essential functions of each type, and saying they mean the same ignores their distinct methods and purposes.
