For example, when I used to work retail, I worked in a community with a largely Russian population. Even when the Wii was dominating and the PS3 was sucking wind, we always had more PS3 sales. So, if you took receipts from our store, it would give you a really skewed view. There is no reason to expect it to be accurate to 5% unless you have some knowledge of their sampling method. Having worked on Black Friday, I can't imagine the sampling method was anything more complex then checking random receipts. |
This app would cover the whole country wouldn't it? Anyone can download it. So I'm sure it's pretty random.
