Definition of «selection bias»

Selection Bias refers to a phenomenon where individuals or groups that are selected for a study, survey, or experiment may not be representative of the larger population. This can lead to inaccurate conclusions and generalizations about the broader group being studied if the selection process is not properly controlled. For example, if a researcher only recruits participants from a specific age range, gender, or socioeconomic background, it may result in an unrepresentative sample that does not accurately reflect the characteristics of the larger population. This can lead to misleading results and conclusions about the broader group being studied.
