Question

Quizplus · Accepted Answer

Lists that give the name of everyone in the targeted audience provide the most precise random sampling because they ensure that every member of the population has an equal chance of being selected for the sample. This method also allows for easy verification of the population and enables researchers to calculate sampling error with greater accuracy. Federal government agencies may have access to these lists, but they may not always be the best source for sampling. Specialized public relations firms and exploratory focus groups do not guarantee a truly random sample.
