So why do so many people (including some on GN) misunderstand averages?
PS. It's a bit of an obsession of mine!
Because they are fairly abstract ideas and because there's 'average' and 'mean' and people get confused.
Many people also don't understand, for example, that if you quote a figure for a nation's average annual income, what it means is that most people earn less than that.
It's still a useful measure though.
Well, people shouldn't get confused. There are three different "averages" (mean, mode, median) and it's important that people understand what is meant.
You're right that some people don't understand that half of people receive less than the median income and there's rarely any indication how low the "tail" of the distribution goes. That's the kind of thing I mean. The average quoted is usually the mean, which is almost always higher than the median.
