Research quality refers to the reliability and validity of the findings produced by a study. It is determined by factors such as the research design, methodology, sample size, and data analysis techniques. High-quality research should be transparent, reproducible, and free from bias, ensuring that the results can be trusted and applied in real-world situations. To assess research quality, various criteria are used, including peer review, ethical standards, and statistical significance. These criteria help to ensure that the research contributes valuable knowledge to its field and can inform future studies, policies, or practices effectively.
