Below are two links you might find useful if you need additional help with SPSS. The first is to the results of a Google search for online SPSS tutorials. I have looked at several of these and think you might find them helpful. The second link is to an SPSS guide provided by Wadworth, the publisher of our textbook. Part of the guide provides a good introduction to SPSS. Hope you find these useful.
