How can external validity be enhanced in a study?

Enhancing external validity in a study is crucial for ensuring that the results can be generalized to a broader context beyond the specific conditions of the research. The option that suggests ensuring the study reflects real-world scenarios effectively addresses this goal.

When researchers design studies that mimic real-world environments, they increase the likelihood that the findings will be applicable to similar situations outside of the controlled setting. This connection allows others to draw conclusions and apply the study's outcomes to different populations and settings, which is the essence of external validity.

For instance, if a study is conducted in a laboratory setting with tightly controlled variables, it may not accurately reflect how those variables interact in everyday life. By incorporating more realistic elements—such as natural settings, diverse participant backgrounds, and practical tasks—researchers can bolster the applicability of their findings, making them more useful for real-world applications.

In contrast, using a narrow sample population can limit the generalizability of the results, increasing the chance that the findings are only specific to that group. Similarly, increasing the complexity of variables may obscure the relationships being studied and complicate the applicability of the results. Limiting the duration of the study might also restrict the insights gained, as certain phenomena may require more time to unfold in order to
