So when you look visually at the distribution of numbers, it looks like the meat of the distribution, so to speak, is in this area right over here. And so some people might say, OK, we have three outliers. These two ones and the six. Some people might say, well, the six is kind of close enough. Maybe only these two ones are outliers. And those would actually be both reasonable things to say. Now to get on the same page, statisticians will use a rule sometimes.
