Dear list member, I am not sure if the right place to ask this question, but I will give it a try. One of my master students wants to compare the performance (e.g., sales) of two retails stores (from the same chain) located in different places in the city. One store is doing better than the other. Hence, the student wants to investigate why is this so. So, he wants to know, what sort of theoretical framework and methodology will be appropriate in this case. What variables need to be considered (in addtion to obvious ones like the location itself). What type of data does he need to collect? so fort. Any pointers will be really helpful.
