Which is an example of potential bias in research?

Asking leading questions to support a hypothesis is a prime example of potential bias in research. This approach can significantly influence the responses provided by participants, steering them towards a specific answer that confirms the researcher's preconceived notions or desired outcomes. When researchers employ leading questions, they compromise the objectivity of the data collected, which ultimately threatens the validity and reliability of the research findings.

In contrast, utilizing a balanced sampling method, asking neutral questions, and choosing samples that reflect cultural diversity are research practices designed to minimize bias and enhance the integrity of the research. A balanced sampling method ensures that all relevant groups are adequately represented, neutral questions avoid influencing responses, and cultural diversity in samples contributes to a more comprehensive understanding of the studied phenomenon. Each of these practices works towards creating a unbiased framework within which research can be conducted effectively.
