What term describes the drawback of survey results when only a portion of the sample responds?

• A. Over 80% returned to work
• B. Disadvantage of Survey
• C. Best way to convey concern, credibility, and sincerity when presenting a speech
• D. Maintain eye contact

Answer: (B)

When only a portion of those surveyed respond, the results may not represent the whole group. This is nonresponse bias, a form of sampling bias where nonrespondents differ in important ways from respondents, skewing the findings. Among the given options, describing this as the disadvantage of a survey best fits, because it directly points to the inherent weakness that occurs when response rates are incomplete. The other choices address unrelated topics—one is about a survey outcome, another about presentation delivery, and another about maintaining eye contact—so they don’t describe the survey limitation. To reduce nonresponse bias, aim for higher response rates through follow-ups, shorter surveys, incentives, or weighting adjustments.
