Hello-

I am interested in comparing mean scores on several attitudinal variables for
two groups: A and B.  I have a dummy variable C (which is coded 0- if group A,
1- if group B).

There is a statistical significance for the difference in the overall means for
these two groups.  However, I want to see whether or not the means for members
of A and B who live in the same neighborhood/city/region are the same.  Some
preliminary cross-tabs suggest that attitudes for these two groups are similar
when analyzed at these geographic levels.

So, I am thinking back to my intro stats class and wondering if ANOVA can test
whether the difference in the mean attitude scores for members of groups A and
B in the same neighorhood/city/region are statistically significant.  If so,
how do I do this?  If not, is there another test I should be using?

Thanks,

-Rahsaan
