Suppose Walmart is planning on locating a new neighborhood store in downtown Richmond. Suppose the city has hired you to report on the net economic and cultural impact of allowing this Walmart in the middle of downtown. Online, you come across many cities reporting traffic statistics in downtowns with a Walmart location. In every large city with a Walmart, traffic statistics indicate considerable congestion. Should you use that data in your analysis? What are the risks in doing so? Could the data be used to skew opinions one way or the other?
