Biostatistics
Non-response bias occurs when individuals selected for a survey or study do not respond, and the lack of response is related to the characteristics of those individuals. This can lead to skewed results that do not accurately represent the entire population, as the views or behaviors of non-respondents may differ significantly from those who participate. Understanding non-response bias is crucial for sampling methods and sample size determination, as it directly impacts the reliability and validity of study findings.
