Assume we want to examine the effectiveness of three therapeutic
interventions (Factor
A
:
a
1
=
group,
a
2
=
individual, and
a
3
=
family) with
Latino community mental health clients. The dependent variable is client
service satisfaction (1
=
very unsatisfied
to 10
=
very satisfied
). Client accul-
turation status (
x
)(1
=
unacculturated
to 5
=
acculturated
) was measured
for each client (
n
=
5) prior to treatment, and served as the covariate. The
data are as follows:
