9/11    What does it mean when they say a group is "self-selecting"?
        \_ Generally the term is used in statistical contexts.  If http://foxnews.com
           puts up a poll on their web site, there are two ways the group
           is self-selected; people who fill out the form chose to go to
           http://foxnews.com, and chose to answer the poll.  Therefore, it is
           hard to draw realistic conclusions from the responses, unless
           you can show that http://foxnews.com visitors are a representative sample
           of the population.  -tom

              polls  --dbushong
