Simple question - need an urgent reply. I had a group of
52 panelists sample and rate 2 separate products. Now I
want to know if the mean ratings for the 2 products are
significantly different. Do I use a paired or

If you want to get a fast reply, you should better to post to
a statistic group in Google not here Choose a group from one
of the following
listing: http://groups.google.com/groups/dir?...%3D46406&q=sta

I think an appropriate group might have been suggested for a rather
simple question but it have been better answered by scanning an
elementary book on statistics. Posing the question in a ng. might
produce both help and rude comments.
