Survey Methodology

As soon as an adequate survey design is set and a solid sample was drawn, infas applies different survey methods – frequently in combination. As a full service institute with resources of its own infas offers:

• quantitative telephone surveys (CATI)
• quantitative face-to-face surveys (paper & pencil or CAPI)
  
• qualitative procedures such as focus groups, guided interviews by telephone or face-to-face or observational research
• postal surveys
• online surveys
• multi-method surveys
