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 telephone?

Telephone interviewing is used when the target group is easy to reach by telephone (e.g., company managers, doctors, clients of a company, etc.) and the survey is short and does not involve visual material. The population is also polled by telephone using quota sampling.
