It's been shown that, in some cases, the group of respondents (and non-respondents) can be inherently biased. It's reasonable to suspect that polarized opinions could affect people's proclivity to respond. You cannot even begin to deal with non-response bias unless you know the non-response rate. And you have no idea what the non-response rate is if you have an open-invitation survey on the Internet. -- Shaun _______________________________________________ desktop-devel-list mailing list desktop-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/desktop-devel-list
