however, the very small sample size suggests that any
conclusions about Native American performance should
be made tentatively. In addition, mean differences
between groups are a function of score reliabilities
(Table 15). Although the reliabilities for the Rainbow
tests are adequate (see discussion above), the brevity of
the tests decreases their values somewhat. Correspondingly,
the levels of reliabilities of the Rainbow scores
should be kept in mind and these group results should be
interpreted with caution.
Although the group differences are not perfectly
reduced, these findings suggest that measures can be
designed that reduce ethnic and socially defined
