8.9 PERFORMING THE OMNIBUS ANALYSIS IN SPSS
8.9.1 STRUCTURING THE DATA FILE
The SPSS data file containing the variables for the analysis of the numer-
ical example we have been using throughout this chapter is shown in
Figure 8.6. That data file is structured as follows. The first variable (col-
umn) is a subject identification code that we have named
subid
.Next
are the independent variables. We have given them arbitrary codes (val-
ues) to represent our categories. For
gender
, females are coded as 1 and
males are coded as 2; for
reside
, large city, small town, and rural com-
munity are coded as 1, 2, and 3, respectively. The final column holds
the dependent variable for the analysis. We have named this variable
lonely
. In this column are the scores on the loneliness inventory for each
participant.
8.9.2 STRUCTURING THE ANALYSIS
We will use the SPSS
GLM Univariate
module to perform the analysis.
