What are nonresponse bias and response bias, and how can researchers reduce them?

• A. Nonresponse bias occurs when nonrespondents differ from respondents; response bias arises from how questions are answered. Reduce via follow-ups, incentives, neutral wording, and anonymity.
• B. They are the same thing.
• C. They cannot be reduced.
• D. They only affect qualitative studies.

Answer: (A)

Nonresponse bias and response bias are two different threats to survey validity. Nonresponse bias happens when people who don’t participate differ in important ways from those who do, so the results don’t reflect the whole population. Response bias arises from how questions are answered—respondents may tell you what they think is socially acceptable, misinterpret questions, or be influenced by wording or order. To reduce nonresponse bias, researchers push for higher participation through follow-ups, reminders, and incentives, and by making surveys easier to complete (multiple modes, shorter length, convenient timing). To cut response bias, they use neutral wording, avoid loaded or leading questions, assure anonymity or confidentiality to lessen social desirability pressure, pretest questions, and consider techniques like randomizing question order or using validated scales. These biases can be mitigated but not completely eliminated. The other statements mischaracterize the issue: they are not the same thing, they can be reduced, and they affect both qualitative and quantitative studies.
