Questions 20-30A survey is a study, generally in the form of an interview or a questionnaire, that provides
information concerning how people think and act. In the United States, the best-known
surveys are the Gallup poll and the Harris poll. As anyone who watches the news during Line
campaigns presidential knows, these polls have become an important part of political life in
(5) the United States.
North Americans are familiar with the many "person on the street? interviews on local
television news shows. While such interviews can be highly entertaining, they are not
necessarily an accurate indication of public opinion. First, they reflect the opinions of only
those people who appear at a certain location. Thus, such samples can be biased in favor
(10) of commuters, middle-class shoppers, or factory workers, depending On which area the
newspeople select. Second, television interviews tend to attract outgoing people who are
willing to appear on the air, while they frighten away others who may feel intimidated by
a camera. A survey must be based on a precise, representative sampling if it is to genuinely
reflect a broad range of the population.
(15) In preparing to conduct a survey, sociologists must exercise great care in the wording
of questions. An effective survey question must be simple and clear enough for people to
understand it. It must also be specific enough so that there are no problems in interpreting
the results. Even questions that are less structured must be carefully phrased in order to elicit
the type of information desired. Surveys can be indispensable sources of information, but
(20) only if the sampling is done properly and the questions are worded accurately.
There are two main forms of surveys: the interview and the questionnaire. Each of these
forms of survey research has its advantages. An interviewer can obtain a high response rate
because people find it more difficult to turn down a personal request for an interview than
to throw away a written questionnaire. In addition, an interviewer can go beyond written
(25) questions and probe for a subject's underlying feelings and reasons. However, questionnaires
have the advantage of being cheaper and more consistent.
