In the survey research design, we describe people's responses to questions about behaviors and attitudes. The four most common methods for administering a survey are mail surveys, telephone surveys, Internet surveys, and in-person surveys and interviews; each has strengths and weakness. Surveys are relatively easy to administer and can be used to obtain information about a wide variety of different variables. However, major weakness of survey research include low response rates, nonresponse bias, and the self-report nature of the design.
