After clicking the SPSS icon, there is a short wait and the SPSS program appears. SPSS 8.0 for Windows begins with two windows. The top window offers several options which may be useful eventually, but the easiest thing to do is close the top window which then gives access to the main program. At this point one of the most sophisticated and popular data analysis programs is available. Thanks to a user-friendly interface, it is possible to do almost anything from the most simple descriptive statistics to complex multivariate analyses with just a few clicks of the mouse. The program is also quite "smart" in that it will not execute a procedure unless the necessary information has been provided. Although it can be frustrating when working with complex procedures, it saves a lot of time in the long run because the feedback is immediate and corrections can be made on the spot.
