What type of data is primarily used in quantitative research?

In quantitative research, the primary focus is on numerically based data, which allows researchers to measure and analyze variables in a structured way. This type of data can be collected through various methods, such as surveys, experiments, or observational studies, and is often accompanied by statistical analysis. The numerical values provide a basis for comparison and can be used to identify patterns, relationships, and causal effects.

By relying on quantifiable measurements, researchers can make generalizations and predictions about larger populations based on a sample. This approach emphasizes objectivity and replicability, making it possible to evaluate hypotheses and validate findings through statistical tests. Thus, the use of numerically based data is essential for drawing conclusions that are grounded in evidence and can be reliably reproduced in future studies.
