Surveys in public places, open, crowded places: Such type of surveys are usually conducted in shopping malls, shopping streets, parks, in fairs and events and other open and crowded spaces. This is one of the best ways to get quick responses through face to face interviews.
Door-to-door surveys: With this type of survey, responses are obtained by visiting the respondents house to house. Such type of surveys are popular in remote areas where there is poor or no Internet connection.
