Well, my initial reaction is that this is a case for -anova-, and you could
obtain further information from

Hamilton (2009), chapter 5, http://www.stata.com/bookstore/sws.html

or

Rabe-Hesketh and Everitt (2007), chapter 4,
http://www.stata.com/bookstore/statanalyses.html

Among free resources, the UCLA website
http://www.ats.ucla.edu/stat/stata/faq/ has a whole section on -anova-.

Also note the command -ttest- to compare means, as well as its cousins like
-signtest- et al. ...

Betreff: st: ANOVA help

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
