The SPSS, as a general statistical software, consists of a wide range of management and analytical procedures that typically cover the needs of even the most demanding and specialized user. Its use - despite its user-friendliness - requires basic theoretical knowledge in Statistics as well as assistance from appropriate manuals and guides. This particular book is a systematic and in-depth guide for the use and data analysis of SPSS that satisfies the needs of even an experienced user. It can be used as an introductory manual by a new user, but also as a detailed guide for data analysis by an experienced user. The former will be introduced to the functional capabilities of SPSS as well as the necessary statistical concepts needed to perform basic types of data analysis. On the other hand, the experienced user will find the necessary details for more effective use of the software, as well as the recommended "solutions" to the issues of complex multivariate analyses. In these more complex analysis cases - which are, however, essential in empirical research - a large part of the book is dedicated with multiple examples from epidemiology, sociology, psychology, criminology, nutrition, and biology.
