SPSS on UCS (Graphical)

SELF-HELP GUIDES > STATISTICS > GRAPHICAL SPSS

Contents
Introduction
Before you can use SPSS on UCS, you must activate your UCS account at the Help Desk, SMH 201. You might also need to work in a class directory or research directory if you are working with large files. If you log into UCS at a workstation, you can bring up the windows version of SPSS and use the mouse and pull down menus. If you log into UCS from another location, using telnet, you can run SPSS on UCS (Non-graphical), i.e., execute a SPSS syntax commands file and create a resulting output file.

Enter Data
There are several ways to read data into the Data Editor window. You can enter data directly, read in a SPSS data file, or read in data from a SPSS system file.

Read Data Directly

    Type numeric data directly into the columns and rows. If you use the numeric keypad, be sure the Num Lock key is on. To enter any data other than numeric, you must first define the variable. To define a variable, click on the column, then Data | Define Variable... See below for a more complete description of Define Variable.

    As you work, save your data. The first time, you must name the file. Under File | Save, click in the Selection box and type survey.sav (or whatever filename you pick, followed by .sav) after /home/abc1234/ and click Continue. After that, File | Save at various intervals. Note: SPSS can be 'tempermental'. If you save as you go, you will not have problems losing valuable data. Also note that the SPSS save file must end in the file extension .sav

    Define the variables (columns). Click on var0001 then Data | Define Variable... You can modify the Variable Name (no more than 8 characters). Click Labels... and assign a Variable Label and Value and Value Labels (after each new value and value label, click Add). When you are finished defining the labels, click Missing if you want to define missing values. When you are completely finished defining the variable, click Continue

Read SPSS Data File

    An SPSS data file has the .sav file extension. Under File | Open | Data... The Open Data file window is displayed. By default, the contents of your home directory are displayed. If you want to select a file in another directory, under Filter, type the directory and wildcard specification and click Filter. For example, if you want to read in one of the SPSS supplied data files, type /pkgs1/spss-6.1.3/data/*.sav Then click one of the files and click OK. The data will appear in the Data Editor window. Alternatively, if you know the pathname of the file, you can enter it in the Selection box.

Read SPSS Syntax File

When you have an external data file with many variable labels and value labels, it is often easier to create a SPSS syntax file and run that, rather than enter all the values using the Data Editor and related windows. Information on creating a SPSS syntax file is found in SPSS 6.1 Syntax Reference Guide. Create the SPSS syntax file using a text editor. Make sure every command ends with a period. Include as the last command line, the command execute. Save the file with the .sps file extension.

Under File select Open then SPSS Syntax... The Open SPSS Syntax window appears. By default, the contents of your home directory are displayed. If you want to select a file in another directory, under Filter, type the directory and wildcard specification and click Filter Then click on the syntax file and click OK. The program appears in the SPSS Syntax window. Under File select Select all and then click the run button (arrow icon) to execute the program. The !SPSS Output window appears. After you have examined the output, you can click on the Data Editor window to make it the active window, or click the Data Editor icon, or under View select Raise Document Window and select the Data Editor window, and continue working with the data.

Save Data or Syntax File

Save Data File

You can save the contents of the Data Editor window. Under File select Save or Save as... In the Save as Data window, click in the Selection box, and type filename.sav (filename does not contain any blanks) and click OK.

Save Syntax File

After you bring up a Statistics command dialog window and have entered all the choices, you can click on Paste. A Syntax window appears with your selections written in SPSS command syntax. You can edit the command syntax or save the commands in a file for use in subsequent sessions. To save a syntax file, under File select Save. In the Save as window, click in the Selection box and type the directory path and filename and click OK. Note that the SPSS syntax file must end in the file extension .sps

As you work in a particular session, any additional commands that you paste from the Commands dialog window are added to the end of the syntax file. If you want to save the contents of the entire session, paste the various commands and then save the entire file before you exit SPSS.

As you work in a Syntax window, you can run the entire file, or select particular commands to run.

The SPSS journal file contains the commands issued during a particular session. After you exit SPSS, in a Terminal window you can copy the journal file:

cp ~abc1234/spss.jnl ~abc1234/program1.sps

Now you can edit the file using a text editor and then use the file in other SPSS sessions.

Problems

SPSS will terminate if you attempt to print without already having selected a printer or if you attempt to print a chart in the Chart Carousel window. Save your SPSS .sav file at frequent intervals, select a printer when you first start SPSS, and use the instructions in this document to print a chart.

If the Chart Carousel window displays a blank screen, under View select Refresh

You can only type commands or use the pull down menus in an active window. Click anywhere in the window (left mouse button) to make it the active window.

Look at SPSS online documentation. Under Help select How to Use SPSS then select Frequently Asked Questions. for answers to the most often asked questions.

Analyzing SPSS Data Files with SAS

SAS can read an SPSS portable file. Save an SPSS data file as a SPSS portable file with the file extension .por and read it in a SAS program with the SPSS engine.

For example, suppose you have created the SPSS portable file /home/abc1234/mydata.por

The following SAS program reads the data file

filename myspss '/home/abc1234/mydata.por';
ibname myspss spss;
proc print data=myspss._first_;
run;

Working with Floppy Disks

In SPSS, you cannot save a file directly to a floppy disk, nor can you read a file directly from a floppy disk. You must copy or save the file using File Manager or mtools in a Terminal window.
mtools
You can copy a UCS file onto a PC formatted floppy disk. Insert the floppy disk into the workstation floppy drive. Bring up a Terminal window and type mcopy ucs_file a:msdos_file The command mdir a: lists the contents of the floppy disk.

You can copy a file from a PC flormatted floppy to your UCS account. Insert the floppy disk into the workstation floppy drive. Bring up a Terminal window and type mcopy a:msdos_file ucs_file The command ls lists the contents of the UCS working directory.

Type man mtools for more information about the utilities to access DOS disks.
