To access my web site and the SPSS/win program on the network from a PC terminal, follow these instructions. Also, note the steps for doing and reporting computer exercises.
Access to Dr. Usip’s Home Page
Action: Double-click on the Netscape Communicator icon on the Windows
Desktop
Result: Access to the Internet; YSU Home page appears.
Action: At the URL (i.e. location) type the address http://www.cc.ysu.edu/~eeusip/
Result: Dr. Ebenge Usip’s Home Page appears. Start browsing the site beginning
with
the Course
Information
Action: Double-click on the SPSS 8.0 program icon.
Result: The SPSS/win program loads. A spreadsheet-like window appears; this is
actually the
SPSS
Data Editor. Before the program can accept instructions for statistical
computation, you must first supply the data set in the SPSS/win format (recall: Data
are the
primary inputs of any statistical analysis). Therefore you must begin your work
by either
creating a data set or loading one into the program (via the A:/ drive) from an
existing
file on your diskette.

To create a file for this data set, each variable must be properly defined. This means that both the data TYPE and the VALUE LABEL (for qualitative data only) must be declared. Let us begin by defining the variable GENDER, which is qualitative.
Action: Double click on "var" in the first column
of the spreadsheet screen.
Result: "Define Variable" window opens. For now pay attention to the
items: "Variable name",
"Type..." and "Labels...".
Actions:
1. Type gender in the "Variable Name" box
2. Click on "Type..." and select String from the list of items. This is
important because gender is
a qualitative variable with non-numeric values (F and M). Click
"Continue" to return to
"Define variable" window.
3. Click on "Labels..." A window that opens.
4 Type Gender of Employees in the "Variable Label" box.
5. Type F in the "Value" box
6. Type Female in the "Value Label" box.
7. Click on "Add". Notice F = "Female" appears. Both the
"Value" and the "Values Label" are
now empty.
8. Type M in the "value" box.
9. Type Male in the "Value Label" box
10. Click on "Add". Again, M = "Male" appears.
11. Click on "Continue" and then "Okay"
Result: Your are returned to the data entry screen with the variable gender
defined. If may
double click on
it to review all the entries you made in steps 1 thru 10.
Follow the above procedure to define the variables: Salary, Education, and Experience. Note that Salary and Experience (in years) are quantitative variables. So you must select "Numeric" under "Type..." If you don’t want two trailing zeros (i.e., no decimal point) after each value enter 0 (i.e., zero) in the "Decimal Places" box of the "Type..." window. Note that Labels are not necessary for a quantitative variable.
