z and t

[dennis roberts]

of course ... if one believes that NEITHER really give you any useful 
information about population parameters ... means ... or correlation 
values, etc.  ... remember, the t distribution and associated tests using 
it, is not JUST used for means ... THEN, maybe this distinction is trivial 
... in all cases ... and the effort needed (and it does take SOME effort) 
to make this distinction is not worth the instructional time devoted to it

but of course, this is just one view in cyberspace ... (and my eudora keeps 
telling me that "cyberspace" is a misspelling .... it needs to get with the 
program!)
