In quantitative research, what factor should be checked to assess validity?

In quantitative research, it's essential to assess both external validity and internal validity to ensure the overall validity of the study's findings. Internal validity refers to the extent to which a study accurately establishes cause-and-effect relationships within the population under study. It ensures that the results are due to the manipulation of the independent variable and not other confounding factors.

On the other hand, external validity concerns how generalizable the study results are to other contexts, populations, or times. It examines whether the findings from the study can be applied beyond the specific conditions or sample used in the research.

By considering both internal and external validity, researchers can gain a comprehensive understanding of their study's robustness and applicability. This thorough approach is essential for ensuring that the conclusions drawn from the research are not only accurate within the experimental setting but also relevant in real-world scenarios.
