Thank you in advance for any help you can provide. I am new to the forum and hope to stick around for a while.

I am working on a research question that seems pretty simple:

Does increased school district level funding mitigate the impact of poverty on student achievement?

The measure of school district level funding = expenditures per student.

The measure of poverty = percentage of students receiving free or reduced priced lunch.

The measure of student achievement = student test scores (Grades 3, 5 and 8 ELA and Math assessments).

I indicated in my methodology, that was approved by my committee, that I would answer this question by using a multiple regression where the assessment scores are the dependent (outcome) variable and the independent variables are both the poverty and achievement variables.

Something about this doesn't feel right to me. Can anyone provide any insight as to whether this will work? (if so, how will the output show whether funding mitigates the impact?) If it won't work, what would?

Thanks!
