SPSS Base 11.0 User's Guide & SPSS Interactive Graphics 10.0

Volume 1: SPSS Base 11.0 User's Guide

SPSS 11.0 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.

SPSS makes statistical analysis accessible for the casual user and convenient for the experienced user. The Data Editor offers a simple and efficient spreadsheet-like facility for entering data and browsing the working data file. High-resolution, presentation-quality charts and plots are integral parts of the Base system. Much of the output from the Base system and Tables option takes the form of flexible pivot tables that you can modify quickly and copy directly into other applications. The Viewer makes it easy to organize and manage your tables and charts using a familiar tree structure. When you have questions about an item in a dialog box, a statistic in your output, or the steps needed to accomplish a task, help is only a click or two away. With the Draft Viewer, you can create simple text output instead of interactive pivot tables. See the overview (Chapter 1) for a list of new features and an introduction to the Base system.

This manual, the SPSS Base 11.0 User's Guide, documents the graphical user interface of SPSS for Windows. Complete information about using interactive graphics can be found in SPSS Interactive Graphics 10.0, which is compatible with release 11.0 of SPSS. Examples using the statistical procedures found in SPSS Base 11.0 are provided in the Help system, installed with the software. Algorithms used in the statistical procedures are available on the product CD-ROM.

Beneath the menus and dialog boxes, SPSS uses a command language that can be used to create and run production jobs. Dialog boxes can "paste" commands into a syntax window, where they can be modified and saved; a few features of the system can be accessed only via command syntax. Complete command syntax is documented in the SPSS 11.0 Syntax Reference Guide, which is included on the product CD-ROM and is available for purchase separately in print. The Help system contains brief syntax diagrams in addition to full help on the graphical user interface.

Volume 2: SPSS Interactive Graphics 10.0

• In the Viewer, start with a blank interactive chart, assign variables to the axes and legends, and specify which graphical elements (bars, lines, a cloud of points, etc.) you want. As soon as you choose each graphical element, it is added to the chart.
• From the Graphs menu, choose Interactive, and then choose a chart type (Bar, Line, Scatterplot, etc.). A dialog box, in which you can assign variables to the axes and legends, specify summary functions, and change appearance attributes before the chart is created, is displayed.

Once you have created a chart, you can make many modifications dynamically. For example, you can insert or delete graphical elements, change colors and textures, rotate 3-D graphs smoothly, and adjust fit lines and surfaces.

This manual is to be used along with the SPSS Base 10.0 User's Guide, which documents the graphical user interface of SPSS for Windows. The User's Guide contains complete information about statistical procedures and the original graphics system (which can be used for types of charts not available in interactive graphics). A companion book, the SPSS Base 10.0 Applications Guide, provides examples of statistical procedures and related data transformations, with advice on screening data, using appropriate procedures, and interpreting the output. Beneath the menus and dialog boxes, SPSS uses a command language that can be used to create and run production jobs. Dialog boxes can "paste" commands into a syntax window, where they can be modified and saved; a few features of the system can be accessed only via command syntax. Complete command syntax is documented in the SPSS Syntax Reference Guide Release 10, which is included on the CD version of the software and is available for purchase separately in print. The Help system contains brief syntax diagrams in addition to full help on the graphical user interface.
