Almost all of us have responded to surveys of one kind or another. We may have been asked what kind of detergent we use, which presidential candidate we intend to vote for, or what our favorite television program is. A survey is a study, generally in the form of an interview or questionnaire, that provides researchers with information about how people think and act. Among the United States' best-known surveys of opinion are the Galiup poll and the Harris poll. As anyone who watches the news during presidential campaigns knows, these polls have become a staple of political life.

When you think of surveys, you may recall seeing many person-on-the-street interviews on local television news shows. Although 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 happen to be

at a certain location. Such a sample can be biased in favor of commuters, middle-class shoppers, or factory workers, depending on which street or 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. As we've seen, a survey must be based on precise, representative sampling if it is to genuinely reflect a broad range of the population.

In preparing to conduct a survey, sociologists must not only develop representative samples; they must exercise great care in the wording of questions. An effective survey question must be simple and clear enough for people to understand. It must also be specific enough so that there are no problems in interpreting the results. Open-ended questions ("What do you think of the programming on educational television?") must be carefully phrased to solicit the type of information desired. Surveys can be indispensable sources of information, but only if the sampling is done properly and the questions are worded accurately and without bias.

There are two main forms of the survey: the interview, which a researcher obtains information through face-to-face telephone questioning, and the questionnaire, in which the researcher uses a printed or written form to obtain information from a respondent. Each of these has its own advantages. An interviewer can obtain a higher 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, a skillful interviewer can go beyond written questions and probe for a subject's underlying feelings and reasons. On the other hand, questionnaires have the advantage of being cheaper, especially in large samples.

Studies have shown that the characteristics of the interviewer have an impact on survey data. For example, women interviewers tend to receive more feminist responses from female subjects than do male researchers, and African American interviewers tend to receive more detailed responses about race-related issues from Black subjects than do White interviewers. The possible impact of gender and race indicates again how much care social research requires (D. W. Davis 1997; Huddy et.al. 1997).

The survey is an example of quantitative research, which collects and reports data primarily in numerical form. Most of the survey research discussed so far in this book has been quantitative. While this type of research can make use of large samples, it can't offer great depth and detail on a topic. That is why researchers also make use of qualitative research, which relies on what is seen in field and naturalistic settings, and often focuses on small groups and communities rather than on large groups or whole nations. The most common form of qualitative research is observation, which we consider next.
