Key Concepts

Sampling Bias

This refers to systematic errors that occur when certain groups are over- or under-represented in the sample. In this context, bias can arise from coverage issues, such as excluding individuals without telephones, or from non-response bias, where those who choose not to participate may differ significantly from those who do.

Random Digit Dialing

This is a sampling technique where telephone numbers are generated randomly to contact respondents. It is intended to provide every household with a telephone an equal chance of inclusion, but it relies on the assumption that all segments of the target population have access to a telephone.
