| Tiivistelmä: | Some of the issues surrounding the use of Internet-based methodologies are studied in this article, particularly the extent to which data from an online survey can be matched to data from a face-to-face survey. Some hypotheses about what causes differences in data from online panel surveys and nationally representative face-to-face surveys are discussed. Parallel surveys were conducted using online panel and face-to-face (CAPI) methodologies, and data were compared before weighting, following demographic weighting and following "propensity score weighting". The article looks at the differences in data from online and face-to-face surveys and puts forward some theories about why these differences might exist. |
