Selection bias is a common problem that can occur when analyzing data that is not fully representative of the information intended to be studied. This can lead to inaccurate conclusions and decisions that are not based on the full picture. A classic example of selection bias is the story of the statistician Abraham Wald and the missing US Air Force planes.
