In-Depth Information
To illustrate how to read the data file (or construct one), consider the
participant coded as
subid
1. That person's information occupies Rows
2 through 6 in the Excel file shown in Figure 10.18. He or she showed
symptom intensities of twelve in the first pretest, twelve in the second
pretest, seven in the first posttest, five in the second posttest, and five in
the last posttest. The next five rows represent the same information in
the same order for the second participant. Each participant's information
is recorded in the same way throughout the data file. More information
on data file structure may be found in Davis (2007) and Slaughter and
Delwiche (2006).
