What type of data does quantitative research produce?

Quantitative research produces numerical data, which is essential for analyzing and interpreting trends, patterns, and relationships within various variables. This type of data is gathered through methods such as surveys, experiments, or structured observations, where responses can be quantified and subjected to statistical analysis. The focus on numerical data allows researchers to apply mathematical techniques to explore correlations and generate generalizable findings about the wider population.

In contrast, the other types of data mentioned—written, verbal, and visual—are characteristic of qualitative research methodologies. Written data would include textual responses or documents, while verbal data pertains to spoken information gathered through interviews or conversations. Visual data involves images or visual representations, which again fall outside the realm of quantitative outputs. Understanding these distinctions highlights the specificity and suitability of quantitative data in providing a clear, measurable framework for social research.
