R (article with link to the download site)
does anybody know a free statistics software for macusers?
i need to run t-tests (t-student) with a huge amount of data (excel-file) so it would be great if you could import data and easily test your hypothesis...
or is there any free ti-89 (titanium) software to run a ti-89 interface on your mac?? i just know something like this exists for windows but neither how its named nor where to get it.
thanks for your help
