Which methods rely on numerical data?

• A. Quantitative methods
• B. Qualitative methods
• C. Mixed methods
• D. Theoretical methods

Answer: (A)

Using numbers to measure and analyze variables is the defining feature of quantitative methods. These approaches rely on numerical data collected through instruments like structured surveys, precise measurements, or experiments. Analysts then apply statistical techniques to summarize the data, identify patterns, test hypotheses, and draw inferences about relationships and effects. Qualitative methods, by contrast, center on non-numerical data such as interview transcripts, open-ended responses, and observations to explore meanings, experiences, and contexts. Mixed methods blend both approaches, using numeric data alongside descriptive data to gain a fuller picture, but the numerical component is essential to the quantitative side. Theoretical methods don’t hinge on collecting new data at all; they develop ideas, models, or arguments through reasoning and existing literature.
