Problem:
You provide a well-organized and balanced discussion of the importance of ensuring similarity between experimental and comparison groups. I appreciate how you clearly explain the role of matching in controlling confounding variables and reducing selection bias, as these steps are essential for strengthening internal validity. Your point about enhanced external validity is also important, particularly when demographic and contextual similarities allow findings to be more meaningfully generalized. I found your discussion of challenges especially strong, as issues such as recruitment difficulty, ethical concerns, and resource demands are often overlooked in practice. The concern you raise about over-matching is particularly relevant, as excessive control can limit variability and reduce the applicability of findings across diverse populations. This highlights the need for thoughtful decision-making rather than rigid methodological rules. As Farmer and Farmer (2020) emphasize, research design requires balancing methodological rigor with ethical responsibility and practical feasibility. This balance helps ensure that research findings remain both scientifically credible and responsive to real-world social conditions. Need Assignment Help?
