Estimating and Testing Hypotheses about Means
E You can enter either a numeric value or a name in the Mean text box. For now, type the
name mn_rec.
E Select All groups. (A check mark appears next to it. The effect of the check mark is to
assign the name mn_rec to the mean of recall1 in every group, requiring the mean of
recall1 to be the same for all groups.)
E After giving the name mn_rec to the mean of recall1, follow the same steps to give the
name mn_cue to the mean of cued1.
The path diagrams for the two groups should now look like this:
These path diagrams are saved in the file Ex13-b.amw.
