Problem
I am investigating the relationship between Walmart stores and effects they have in their surrounding areas in the way of prices and wages to infer whether Walmart's are good for local economies.
I'll set up my hypothesis as:
Null Hypothesis: New Wal-Mart stores negatively impact wages and prices in communities
Alternative Hypothesis: New Wal-Mart stores do not negatively impact wages and prices in communities
Where the independent variable in this case is the number of Walmart stores in an area and dependent variables will be wages and prices.
My question is, how would you go about collecting data for this type of study and what methods can be used for heteroskedasticity and measures to correct standard errors?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
