A form used by sociologists to obtain comparable information from respondents but that does not require face-to-face contact is a questionnaire.
A questionnaire is a research tool made up of a list of questions used to collect data from respondents during a survey or statistical analysis. Typically, a research questionnaire will have both closed-ended and open-ended questions.
A questionnaire is a very practical tool for quickly gathering data from a big number of people. Therefore, the questionnaire's design is crucial to ensuring that correct data is gathered and that the findings can be interpreted and extrapolated. When a fresh approach is required for a research subject, questionnaires are frequently chosen as the solution. Sometimes a questionnaire can only be utilized as a part of a mixed methodological study, such as when extending and quantifying the results of an early exploratory stage.
