ABSTRACT
Since the different kinds of statistics to be described in this book will be carried out with one of the, if not the, most widely used and comprehensive statistical programs in the social sciences, SPSS, we will begin by outlining what this entails. The abbreviation SPSS stands for Statistical Package for the Social Sciences. This package of programs is available for both personal and mainframe (or multi-user) computers. These programs are being continuously updated and so there are various versions in existence.
