A survey consists of obtaining information from a respondent on the basis of a pre-prepared questionnaire.
Unlike questionnaire interviews, surveys involve respondents answering questions and recording answers on a paper or electronic questionnaire. The interviewer’s role in research conducted using questionnaires is limited to recruiting interviewees and distributing questionnaires to respondents.
Questionnaires fall into the following categories: paper-based, online and auditorium questionnaires. The latter involve respondents being gathered in a single room and completing their questionnaires, following which the completed questionnaires are pooled. Three types of questions can be asked in questionnaires: open-ended, semi-open-ended and closed-ended questions.
