Today, a large and increasing number of quantitative studies are making use of online interviewing and data collection. This technology evolution is occurring rapidly, and research institutes have questions about it, notably concerning the representativeness of Internet users but also in terms of the quality of the responses obtained. A variety of studies have been carried out on the subject of sampling: How can we build a reliable sample base while optimizing response rates? Is it possible to obtain information that is pertinent for a larger population simply by interviewing Internet users (for example, for Internet
users and non-users), and under what conditions? ... Other research has focused on comparing the results of offline research (face-to-face and phone) with those of online studies.
