Multi Modal Example trying to assess correct Statiscal approach

I am trying to figure out the best statistical approach to address a problem. I am looking at 100 retail stores and looking at their hourly traffic. Trying to determine the best method to determine which locations have the largest amount of variable traffic. Any Thoughts?

I certainly would appreciate anyone thoughts here.
Hi, so you have for each store several hourly measurements [math]x_1,x_2,...,x_n[/math] and you want to determine the store with the highest average value?
