The SPSS for Windows program needs to be copied to your hard drive and run from the hard drive. The CD will provide you with a menu of choices each time you insert it in your CD drive. One of the choices is to set up the program on your computer. You only need to do this once.
The version of SPSS for Windows included free with this text is the student version. It will perform most, but not all, statistical analysis procedures. It will operate for thirteen months from the time you first install it on your computer.
