What type of research is characterized by the collection of numerical data?

Quantitative research is characterized by the collection of numerical data, which allows researchers to quantify variables and identify patterns, relationships, or trends through statistical analysis. This type of research is often used to test hypotheses, make predictions, or examine correlations between different factors. By utilizing structured tools such as surveys, experiments, or existing data sets, quantitative research provides a systematic approach to collecting measurable data, enabling researchers to derive conclusions that can be generalized to a larger population. This approach contrasts sharply with qualitative research, which focuses on exploring concepts and understanding experiences through non-numerical data, such as interviews or observations.
