Though most of its advancements over the past decade or two have been geared toward corporate and marketing interests and needs, SPSS is still widely used for social science research as well as other disciplines. Its greatest asset, and one might argue its primary strength relative to the other general purpose packages, is a user interface that makes it easy to perform analyses, some even quite complex (though most major stat packages have some graphical user interface these days).
Due to its popularity, you'll find many guides and resources directing you on use of SPSS. We've included some helpful resources below.
