Preface
SPSS 13.0
SPSS 13.0 is a comprehensive system for analyzing data. SPSS can take data from
almost any
type of file and use them to generate tabulated reports, charts and plots of
distributions and trends, descriptive statistics, and complex statistical analyses.
This manual, the SPSS® Base 13.0 User’s Guide, documents the graphical user
interfac
e of SPSS for Windows. Examples using the statistical procedures found
in SPSS Base 13.0 are provided in the Help system, installed with the software.
Algorithms used in the statistical procedures are available on the product CD-ROM.
In additi
on, beneath the menus and dialog boxes, SPSS uses a command language.
Some extended features of the system can be accessed only via command syntax.
(Those features are not available in the Student Version.) Complete command
syntax i
s documented in the SPSS 13.0 Command Syntax Reference, available on the
Help menu.
