Survey (human research)
Survey research is often used to assess thoughts, opinions, and feelings. Surveys can be specific and limited, or they can have more global, widespread goals. Psychologists and sociologists often use surveys to analyze behavior, while it is also used to meet the more pragmatic needs of the media, such as, in evaluating political candidates, public health officials, professional organizations, and advertising and marketing directors. A survey consists of a predetermined set of questions that is given to a sample. With a representative sample, that is, one that is representative of the larger population of interest, one can describe the attitudes of the population from which the sample was drawn. Further, one can compare the attitudes of different populations as well as look for changes in attitudes over time. A good sample selection is key as it allows one to generalize the findings from the sample to the population, which is the whole purpose of survey research.
SurveyUSA
SurveyUSA is a polling firm in the United States. It conducts market research for corporations and interest groups, but is best known for conducting opinion polls for various political offices and questions. SurveyUSA conducts these opinion polls under contract by over 50 television stations (who also use the SurveyUSA market research to fine-tune their newscasts for higher ratings).
The difference between SurveyUSA and other telephone polling firms is twofold. First, SurveyUSA does not use live call center employees, but an automated system. Taped questions are asked of the respondent by a professional announcer (usually a local news anchor), and the respondent is invited to press a button on their touch tone telephone or record a message at a prompt designating their selection. Secondly, SurveyUSA uses more concise language, especially for ballot propositions, than competitors. This can lead to diverging results, such as for California Proposition 76, where one version of the SurveyUSA question with a one sentence description, polled significantly differently compared to another version with a three sentence description (which was similar to a version of the question used by other pollsters, which used a five or six sentence question).
