We carry out all methods of data collection.

The three basic methods of data collection are: personal interviewing (CAPI, PAPI), telephone interviewing (CATI) and Internet interviewing (CAWI, CASI). These methods can be combined and it is possible to recruit respondents by one method and question them by a different method.

Advantages and disadvantages of different methods of data collection

All types of data collection (interviewing, field collection) have their advantages and disadvantages and the selected method depends on the specific assignment.

The best known method is the personal interview. This can be used for longer and more complex questionnaires, but is more difficult to design and manage and more expensive.  It is not really suitable for questioning on sensitive topics where people tend to conventionalise their answers.

Telephone interviewing is more anonymous. Unless previously agreed, it should be concise (short call duration) and as clear as possible (telephone questioning). If not otherwise pre-arranged (materials sent etc.), it is limited to verbal communication.

Internet polling is currently the fastest and least expensive type of data collection. In applying this method it is advisable to consider, with respect to the research questions, how Internet users differ from the defined target group, in order to interpret the research outputs correctly.  Internet research can be complemented with other methods of data collection.

Most commonly, Internet polling is done by means of an Internet panel of respondents. The indisputable advantage of the Internet panel is the possibility of using targeted recruitment and the use of regularly updated information about the respondents. You can find more information about our Internet panel here. Data collection by Internet questionnaire can also be carried out through customer databases (e.g. Employee surveys).

Nowadays, Internet polling is involved to a large extent in qualitative research. On the Internet you can organise online focus groups independent of  the respondent’s location, important discussion forums (blog groups) or individual interviews. We also conduct qualitative surveys in person or by telephone.

We always select the method of data collection according to research objectives, target groups, timetable and available budget.
