Thanks for posting the game! Sadly I found this thread too late - let me contribute a bit to it. I probably would not have qualified on merit anyway.

These are the calculated numbers from the 182 posted numbers/members:

Average: $13,452
Median: $11,500
Mode: $10,000 (calculated on values rounded to nearest significant digit ~ rounding to nearest $100/$1,000/$10,000 gave the same result)

I doubt the price will be below $7,200 or above $14,400. My personal guess: $11,888
(I understand I am not eligible to win anymore - guessing just for the sports.)

Statistics 101:
Average = Also known as mean - you add up all the numbers and then divide by the number of numbers.
Median is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median.
Mode is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list. (hence rounded to $100 and $1,000)
