Survey error is the
extent to which findings from the survey sample differ from those
of the population of interest. The large nationally representative
surveys discussed here are designed to minimize error. Nevertheless,
it is impossible to eliminate all of the multiple potential sources
of error. Investigators must identify and consider how potential
survey error can bias the results of their analyses. Statistical
strategies can minimize the impact of these potential sources
of error on study findings.
