As I recall from a statistics class I took, and didn't do very well in, a long time ago, there are different kinds of averages.
The one Wandeljw used is the most common. The Aritimetic Mean. Add up the scores predicted by the players and divide by the number of players. Wandeljw came us with the A2K consensus as being Colts (25) -Bears (23).
I did the same exercise (also excluding JPihicago but with 21 players). What I did was add up the points that those picking Indy thought Indy might score and I divided by the 11 of us who have Indy. Indy comes out at 31. Chicago, using the 10 players picking them, ends up at 30.
The problem with the Arithmetic Mean is that is can be drastically skewed by a wildly extreme pick, particularly if the number of players is small.
Another Average is called, I believe, the Median Average in which the picks are listed in ascending or descending order. And the one in the middle is the Average. Using this method, the pro-Indy folks have their team at 30 while the Bears are at 31.
There is another Average called, I believe (but I may be wrong) the Mode.
This is the number picked by the largest number of players going for Indy or Chicago. Three of us have Indy at 28. Two of us have Chicago at 31.
How mind-numbing and thread-stopping was that? And I think I just heard one of yall mutter, thank god we are rid of johnboy.
Remember: statistics don't lie. Statisticians do.
