SAS is a comprehensive statistical package that comes well
equipped to handle many of the needs of the applied researcher, though it, like
SPSS, is perhaps even more popular for marketing and business needs in general.
SAS is very powerful out of of the box and capable of a wide variety of
analyses. It is command line driven first and foremost, though SAS Enterprise
Guide offers menu capability. It is more functional than SPSS base, and also
uses a macro system like SPSS to add additional functionality. They can be seen
as similar in their programming languages as well, as such if you are choosing
between SAS or SPSS you would probably want to go with the former.
