Key Concepts

Sampling Frame Limitations

A sampling frame is the source material from which a sample is drawn. The voter registration list, as a sampling frame, includes only those who have registered to vote, thus inherently excluding eligible adults who choose not to register, which limits its utility as a comprehensive census.

Population Census

A population census aims to count every individual within a target group, typically providing a complete profile of the adult population. In contrast, a voter registration list only includes those who have chosen to register to vote, failing to account for every adult in the community.

Coverage Error

Coverage error refers to the discrepancy that arises when a data collection method does not fully or accurately capture the intended population. Since the voter registration list omits non-registered adults, it does not serve as a reliable census of the overall adult population.

Self-selection Bias

Self-selection bias occurs when participation is voluntary, resulting in a sample that may not be representative of the entire target group. With voter registration, individuals who register might share certain characteristics, leaving out segments of the adult population that are less inclined or unable to register.
