I am currently studying a rate of a procedure and how does the rate differ between races. It appears that the procedure is more offered to Hispanic patients than any race and is more done in the southern region of USA. By knowing that Hispanic race is more in the south too as the procedure, is there any type of statistical tool that can deal with that? I mean adjust for that?

It would help a lot if you could provide more information. What kind of measurements are these? It seems like you may be referring to the amount of time to complete a task, but it is not clear. Also, how does the geographic component come into the question? – Macro Jan 17 at 1:22

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.

This is more a conceptual answer than a practical tool, but my very basic first step would be to try splitting your data:

1) Considering just the southern (or northern) US, is the proportion of Hispanics receiving the procedure greater than the proportion of people of another race?

2) Considering just Hispanics (/those of another race), is the proportion of people receiving the procedure greater in the southern US than in the northern US?

**Edit: also, consider that it's probably quite easy to find census stats on reported race/ethnicity at the state level, which would give you a finer distinction that just northern/southern.
