Convenience or calamity? Pharmaceutical study explores the effects of sample frame error on research results.
Survey results of a nationwide sample frame did not differ from those of a statewide sample frame with respect to questions that were professional/procedural in nature or that dealt with putative industry knowledge. However, on questions that were attitudinal in nature, the sample frames differed significantly. Because of this, the authors conclude that using a geographically narrow convenience sample may or may not result in frame error, depending on the information being sought.
