What defines quantitative research?

Quantitative research is characterized by its focus on numerical data and statistical analysis. This approach is used to quantify variables, establish patterns, and derive objective truths from the data collected. Researchers in this field often implement structured tools such as surveys, experiments, or observational studies that yield quantifiable information. By analyzing this data, researchers can draw conclusions that are intended to be unbiased and applicable to broader populations, thereby facilitating generalizability of findings.

The other options do not align with the defining principles of quantitative research. The collection of qualitative narratives reflects a qualitative approach, which emphasizes subjective experiences and personal perceptions. Focusing solely on personal experiences and understanding subjective perceptions are also hallmarks of qualitative research, where the goal is typically to gain insights into individuals' feelings and thoughts rather than statistical analysis. Thus, the emphasis on numerical data and objective analysis is what distinctly defines quantitative research.
