SPSS for Windows is a powerful statistical package for data analysis. Many tasks can be accomplished by simply pointing and clicking the mouse. The following movie clip will take you through various windows and utilities that are available for users. This tutorial tries to cover both SPSS 9.0 and 10.0. There are some differences between these two versions. The major difference is on the creation of variable labels, value labels and missing values. In this tutorial, we will discuss the differences as needed. However, since this tutorial was developed originally for Version 9.0, you may experience some changes in version 10.0, which may not be addressed in this tutorial. Please let us know if you experience such differences. You can start SPSS for Windows using either of the following ways: (1) If you already have the SPSS icon on your desktop, double click on the SPSS icon. OR (2) Go to Start Menu | Programs | SPSS 9.0 (or SPSS10.) for Windows. Click on the following movie clip to see Overview
of SPSS: |
There are a number of different types of windows in SPSS. The window in which you are currently working is called the active window. Some of the frequently used windows are:
| Data Editor Window: It displays the contents of the
data file. This is the window that opens automatically when you start an SPSS
session. In this window, you can create new data files or modify existing ones. | |
| Output Viewer Window: It displays statistical
results, tables, and charts. This window opens automatically the first time you run
a procedure that generates output. |
| Chart Editor Window: This window is used to edit
regular charts and plots. |
| Syntax Editor Window: It displays the choices made in the dialog box in the form of command syntax. These commands can be edited and run to get some output. You can also copy an old SPSS program here and run it. |
Many tasks in SPSS are performed by selecting appropriate
"pull-down" menus. Each window in SPSS has its own menu bar with
appropriate menu selections and toolbars. The Analyze and Graphs menus are
available in all windows. Here are some Data Editor window menus and
their uses:
| File: To open an existing file, to read data (from a text
file or from an application [like Excel] file) into Data Editor window, to save
the data file, and to exit SPSS for Windows. | |
| Edit: To make changes like copy, cut or paste to the Data
Editor window. | |
| Data: To define variables, insert variables or cases, sort
cases, merge files, split files, select cases and use a variable to weight cases. | |
| Transform: To do some computations on variables, to create
new variables from existing ones or recode old variables. | |
| Analyze: To do statistical analysis, from descriptive
statistics to testing of hypothesis. | |
| Graphs: To obtain high resolution plots and graphs, which
can be edited in Chart Editor window. | |
| Utilities: To run script and to display information on the
contents of SPSS data files. | |
| Window: To move to any open window or to see which window
is active. The window with a check mark is the active one. | |
| Help: To get help on topics in SPSS and to ask the statistics coach some questions. |
Each window in SPSS has its own toolbars that provides access to common tasks. Some windows have more than one. When you put the mouse pointer on a tool, there is a brief description of what the tool does. You can show, move or hide a toolbar.
The status bar is at the bottom of each SPSS window and provides the following information:
Command Status: gives information about a procedure that is running. | |
Filter Status: Filter On shows when a subset of cases in the data is used for analysis. | |
Weight Status: Weight On indicates that a weight variable is being used in the analysis. | |
Split File Status: Split File On indicates that the file has been split into separate groups for analysis. |
Many menu selections will open dialog boxes. In these dialog boxes, you select variables and options for analysis. The main dialog box in any statistical procedure has the following parts:
Source variable list: A list of variable types (allowed by the procedure) from the working data file. | |||||||||||
Target variable lists: One or more lists of variables needed for the analysis. | |||||||||||
Command push buttons: Buttons that can be used to run the procedure by opening a subdialog box to make additional specifications. Some of the push buttons are:

In a dialog box with source variables,
numeric variables are indicated by:
