Bias in research is any systematic error that distorts findings away from the true result. It can enter a study at every stage, from how participants are selected and how data is collected to how results are analyzed and reported. Unlike random error, which averages out with larger samples, bias

Research ethics is the set of principles and procedures that protect the rights, safety, and well-being of human participants in research. It governs how researchers collect data, obtain consent, maintain confidentiality, and report findings.
