The test of effect sizes using the Cohen's d statistic
allows one to consider more specifically a standardized
representation of specific group differences. The Cohen's
d statistic is represented in Table 15. For the test of ethnic
group differences, each entry represents how far away
from the mean for Whites each group performs in terms of
standard deviations. For the test of gender differences, the
entries represent how far away women perform from men
in terms of standard deviations.
These results indicate two general findings. First, in
terms of overall differences represented by omega
squared, the triarchic tests appear to reduce race and
