Conclusion on external validity.
External validity is a cornerstone of scientific research that determines the real-world applicability of study findings. While you must be cautious of potential threats that can compromise external validity, you can employ various strategies to enhance the generalizability of your results. Diverse sampling, conducting studies in natural settings, randomization, replication, and meta-analysis are all tools that you can use to ensure that your conclusions resonate beyond the confines of your immediate study. By diligently addressing external validity concerns, you contribute to the credibility and practical relevance of your work, ultimately advancing our understanding of the world around us.
