Quantitative surveys involve the use of structured questionnaires developed and customized to the client’s needs by professionals of economics and marketing. The main aim of quantitative surveys is to poll a certain portion (sample) of the target group using a structured questionnaire and, having analyzed the obtained data, to generalize the results for the whole population.
When are surveys conducted by face-to-face interviews?
Face-to-face interviewing is used when the target group is hard to reach by telephone and internet or when the aim of the research is to carry out a representative survey. This method is also handy when a survey is complex, long and involves additional means (e.g., visual material).
