The Internet is now increasingly being used as a tool for quantitative research. In the thirties and forties, the only ways to collect data from a quantitative survey were by mailing questionnaires or interviewing respondents by going door to door. Since the 1970s, telephone interviews have become a popular alternative, thanks to the almost universal adoption of the telephone. Today, as the Internet is becoming more and more widely used, web surveys are becoming an increasingly interesting option. However, the Internet has not been universally adopted by all households. Although the number of people and households with access to the Internet is constantly growing, its use is not universal and therefore Internet research is becoming partially problematic (Dillman et al, 1998a: Van Dijk, 2000: Crawford, et al, 2001). .; Miller et al., 2002).
