To most of us the average (mean) is obtained by simply adding the numbers and dividing that total by the number of values in the list. Thus (13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13) ÷ 9 = 15. 15 is the average (mean) but oops - it's not in the list but that's the way the mean crumbles.

But like many things the average can be spun to suit the argument involved - thus we can use the median - the middle value. 13, 13, 13, 13, 14, 14, 16, 18, 21 - 14 is the middle value. Hey - at least this average is in the list.

For the truly esoteric there's the mode - yet another statistical average - and it references the number that occurs most frequently in the list. That number is 13 and hey - it's in the list too.

The moral of the story? Here we have 3 answers to the same question. 15, 14 and 13. Know your numbers before accepting any statistical values quoted in any discussion. Statistics can be used to support darn near anything - any spin on a topic. That's why a single source for things is in my opinion not a smart thing to use/believe. Especially if a politician or newscaster is involved.
