Quantitative data research is focused on collecting and analyzing numerical data, which enables statistical analysis. This type of research is designed to quantify variables and uncover patterns or trends within the data. Common methods associated with quantitative research include surveys, experiments, and observational studies where measurements are made on various attributes, allowing statisticians to apply mathematical and statistical techniques to the data.

By relying on numerical data, quantitative research offers the ability to generalize findings across larger populations, thereby enhancing the reliability of conclusions drawn from the analysis. It is distinct from qualitative data, which relies on descriptions and characteristics rather than numbers, and mixed methods, which incorporate both qualitative and quantitative elements. Descriptive data, while it may be derived from quantitative studies, does not focus inherently on numerical analysis but rather on summarizing and describing the data without delving into deeper numerical relationships or statistical tests.
