Why is Nonresponse Bias a Concern in Epidemiology?
In epidemiological studies, obtaining accurate and representative data is crucial for understanding health trends and making informed public health decisions. Nonresponse bias can lead to systematic errors that distort the true picture of a population's health status. For instance, if nonrespondents are more likely to belong to a particular demographic or have specific health conditions, the study's findings may not accurately reflect the reality.
