[Air-L] Text Sample Size?

[Karyn Hollis]

   Hi All--
   This is a newbie question.  I am planning to do a quantitative data
   analysis to study blogs for gender differences in CMC.  Are there any
   rules for the size of samples?  Would comparing male to female blog
   texts of a total of 50,000 words each be enough to claim statistical
   significance for any differences I find?
   Thanks for any advice,
