In order to make the research unbiased it requires that answer?

To make research unbiased, it is crucial to ensure that the study design is objective, with clear methodologies that minimize personal or societal influences on the outcomes. This can be achieved by using random sampling, employing blinding techniques in data collection and analysis, and avoiding leading questions in surveys. Additionally, researchers should strive to report results transparently, acknowledging any potential conflicts of interest and limitations in their study. Finally, peer review and replication by independent researchers can further validate the findings and reduce bias.
