The median is simply the middle number of the sample here. The data isn't distributed normally, the mean is over $5000 and the SD over $26000.

Should have used log scale (seriously!) i.e. use the geometric mean instead of arithmetic mean,
and compute the SD by exp(sqrt(sum((log(P(i)) - log(Pmean))^2))).

Can't we just go ahead and determine the median values with the 5 most accepted ways there are? Hell, we could even introduce the super-meta-mean-index Cheesy

Hey, thanks. I have ~$480 for the geometric mean, and ~10.5 for the geometric SD. If I understand this right, the geometric standard deviation is multiplicative, so 1sigma would be 480*10.5, 2sigma 480*10.5^2, while -1sigma would be 480/10.5?

Yes, that's correct, thanks!

$30,000.00 USD

because
a) This would still be less than the change in 2013, and
b) What would be the point of winning if the current trend hasn't changed by then?   Grin
