Common source bias
Type of selection bias and source of logical errors
Common source bias is a type of sampling bias, occurring when both dependent and independent variables are collected from the same group of people. This bias can occur in various forms of research, such as surveys, experiments, and observational studies. Common source bias is a significant concern for any study as it can lead to unreliable results.[1] It is most prevalent in the field of public administration research, where performance measures subject to common source bias can produce false positives when organisational performance is evaluated with explanatory and perceptual measures from the same source.[2]
