What characterizes quantitative research?

Quantitative research is primarily characterized by its focus on collecting and analyzing numerical data that can be measured and quantified. This approach allows researchers to gather data from larger samples, enabling the findings to be generalized to a broader population. The emphasis on numbers and statistical analysis means that the results can be projectable, providing a solid foundation for making predictions, identifying trends, or testing hypotheses within a particular study.

In contrast, other options do not align with the essence of quantitative research. For instance, gathering qualitative insights typically involves techniques like interviews or open-ended surveys, which emphasize descriptive data rather than numerical metrics. Reliance on anecdotal evidence falls outside of the structured methodology essential to quantitative approaches, as anecdotal evidence is often subjective and lacks the rigor required for effective data analysis. Lastly, focusing on small group analyses is more indicative of qualitative research, which aims to understand deeper insights and dynamics rather than seeking to quantify results across larger populations. Thus, the defining characteristic of quantitative research is its provision of numerical, projectable data.
