Simultaneous Analysis of Several Groups
E
In the Variance text box, enter a name for the variance of recall1; for example, type
var_rec.
E Select All groups (a check mark will appear next to it).
The effect of the check mark is to assign the name var_rec to the variance of recall1 in
all groups. Without the check mark, var_rec would be the name of the variance for
recall1 for the young group only.
E While the Object Properties dialog box is open, click cued1 and type the name var_cue
for its variance.
E Click the double-headed arrow and type the name cov_rc for the covariance. Always
make sure that you select
All groups.
The path diagram for each group should now look like this:
var_rec
recall1
var_cue
cued1
cov_rc
