Quantitative data refers to what type of information?

• A. Descriptive narratives and case studies
• B. Numerical data used to identify patterns and relationships
• C. Qualitative interviews
• D. Observational notes

Answer: (B)

Quantitative data focuses on numbers and measurements. It is information that can be counted, scored, or measured, and it’s analyzed to identify patterns, trends, and relationships through numerical methods. This numeric nature makes it possible to compare groups, track changes over time, and test hypotheses with statistics or math.

Descriptive narratives and case studies, descriptive in nature, and qualitative interviews provide non-numeric details about experiences, opinions, or contexts. Observational notes often capture rich, descriptive information rather than numbers. So they belong to qualitative data.

Therefore, the description that fits best is the one that talks about numerical data used to identify patterns and relationships. That’s what quantitative data is all about.
