In order to have variability, I have to have multiple data points, and it should be at least possible that they could vary. So for example, all of these folks ate zero bricks, and maybe it was possible that someone actually ate a brick. But here I just have one data point. With one data point, you can't have variability. So this is not a statistical question. I just collect a data point. Next question, what is the average number of cars in a parking lot on Monday mornings?
