the average new car sold in the US last year cost $31K
Aside (
not aimed at ArtOfWarfare personally):
Beware averages (assuming "average" to mean "arithmetic mean" unless otherwise stated). They tell you very little unless you know the data has something resembling a normal distribution, ie. a nice, symmetrical bell curve.
Car prices range from, what, $10K ball park, through $100K "luxury" cars bought by the 10%ers to $1M supercars for the 1%ers. Plug those 3 very crude guesses into a spreadsheet and you'll get an average price of about $28K - now "downgrade" the 1%ers from a $1M Bugatti to a $500K Ferrari - a change which doesn't affect 99% of the population - and it knocks the average down by $5K. That's *not* meant to be a credible estimate of anything real BTW (for starters, what fraction of the population actually buy brand new cars?) the point is how much changes to the extreme end affect the average.
Generally, if you don't know what the distribution is like, the median is more useful than the mean since then, at least, you know that 50% of car buyers paid the median or above. That's probably why it never gets published
Same applies to "average wage" which is disproportionately inflated by very high earners, although in that case "median wage" seems to have caught on, especially when journalists really want to mix it by
comparing median earnings with average new car price. D'oh! (Mind you, 50% of the population suffering the ignominy of having to buy a
used car is hardly the most damning inditement of the inequality of society you could come up with).
Bottom line: nobody should be taught about averages (including mean, median, mode) without being made to spend some time looking at graphs of real data and understand that all of these simple measures can be hugely misleading... and if anybody wants to write an article about some statistics
put the bloody graph in! We live in the age of immersive IT - it takes minutes - why are we rooted in the days when a graph meant half a day's work for a clerk and a draughtsman?
