Which factor might indicate poor quality in a strong evidence study?

Inadequate research methods are a significant indicator of poor quality in a strong evidence study. Research methods encompass the study design, data collection techniques, and analysis processes. If these methods are flawed, the findings can be unreliable, invalid, or biased, leading to conclusions that do not accurately represent the truth. The rigor and appropriateness of research methods are paramount for ensuring that the results can be replicated and applied correctly within the field.

On the other hand, high sample size usually correlates with greater statistical power and is generally seen as a strength in research design. Publication in a peer-reviewed journal suggests that the research has undergone evaluation by other experts in the field, which is an indicator of quality. Clear result interpretation is essential as it helps in understanding and applying the research findings, and doesn't inherently reflect on the quality of the study itself but rather on how the results are communicated.
