Right, but this is selection bias. There will always exist a distance D from which all bad kebabs are located.
Unless D is provenly chosen _before_ looking at the data, this has no meaning.
One also has to take the kebab density into account.
- estsauver 2y agoThis "you have to choose D" ahead of time nonsense is why people distrust and dislike statisticians! Humans have priors on what is "close" that are independent of this particular article. If they had said "See, everything within 5000m" or "everything within 5m" you might have a point but "500m" being a rough definition of "close to a train station" is pretty reasonable.
