Administering surveys requires careful planning in several areas. When writing questions for a survey, the content, scope, and purpose of each question must be determined, as well as the appropriate response format and wording. Feasibility factors like costs, facilities, time, and available personnel also influence survey design and administration. Different types of surveys like structured questionnaires, unstructured interviews, and contingency questions each have their own advantages and challenges to consider. The role of an interviewer includes locating respondents, gaining their cooperation, motivating high quality responses, clarifying any confusion, and properly conducting the interview.
