Actually you can't even conclude that. This opinion
poll was not
conducted in accordance with modern statistical theory. Polling
can't
work without random sampling. Can you tell us what the margin of error
is for your findings? I only thought that as members of a
scientific
community we all should understand that the results you claim are
reliable are completely unreliable.
I suppose you should have asked my mother-in-law. Now that
would have been random!!
I only commented on this from a
scientific point of view. I have no
interest in blades. I don't make
them. I don't sell them. I don't use
them.
A poll is a poll. You ask for input. You collect the
answers, you present them to this list server, no-one asked for them to be published in a journal.
Furthermore, I never said that
opinions are meaningless. I only said
that the manner in which you gathered,
tallied and presented the
information is meaningless. Your 4:1 margin
claim has no basis in
reality.

Cliff,
you are looking for science where there can be none. I
asked the list
for the preferences (which are subjective opinions) of those
who have
evaluated different blades. The most that can be concluded from this
poll is that more people buy AccuEdge (by a 4:1 margin) than
other
brands. Since this blade costs more, I would presume that those using
it
feel that the additional cost is worth it.
Is it really your
intention to tell those who responded to my query
that their op;inions
are meaningless? All I did was count up the replies
and convert to a percent
based upon the total number of responses to
the
question.

Vinnie,
In fairness to all the companies making blades,
and to those who are
using
them as well, everyone should be aware
that your <<survey>> has has
no
statistical merit
whatsoever. This has not been a science behind your
poll
in
completely skewed so the results are meaningless.
