at random. That hypothesis is less likely than the more obvious one.
It would be very difficult to hit upon a random cross section of the
delegates who behaved like that.
What might skew the figures could be the way the sample was taken. If,
for example, the questionnaire was given to people who came to some sort
of Linux stand, then it could potentially be a most un-representative
sample. If the figure is 45% of "people who expressed a general interest
in Linux", then it is probably pretty meaningless. If OTOH it was
a genuinely random sample of those attending, and they were presented
with the survey under no specific OS heading (I.e. it wasn't portrayed
as "A survey of Linux usage", but merely as a general gathering of
information) then the 45% figure could be deeply significant.
(Newsgroups heavily trimmed. Follow-ups trimmed even more.)
