SAS, SPSS, or Systat?

[Jeffrey Nipp]

We have access to site liscenced copies of the windows versions of SAS, 
SPSS and Systat.  We are looking for an easy to use stat package which 
will handle clinical research studies with tens to hundreds of patients 
and multiple variables.  I am nearly statistics illiterate, and the rest 
of the lab is not much better, so HELP facilities are a big plus as 
well.  Any suggestions on which package would be best?  From looking at 
the manuals, Systat looks to be the easiest to use, but we'd like to hear 
it form someone who knows what they are talking about!  :)


Thanks!
Jeff
