| Tiivistelmä: | This study reports the findings of a comparison btw. different non-probability sampling methods applied in a WWW-user-survey. Respondents were recruited in four different ways. The results indicate i.e that 1. newsgroup postings and e-mailings generate very high speed response, 2. all non-probability sampling methods possess different caveats which force researchers to apply them cautiously, 3. the recruitment methods generate responses of equal quality and completeness, 4. the various recruitment methods are not suited for generating stable results etc. |
