The big difference between the median and average is illustrated in a simple example.
Suppose 19 paupers and 1 billionaire are in a room. Everyone removes all money from their pockets and puts it on a table. Each pauper puts $5 on the table; the billionaire puts $1 billion (i.e.$109) there. The total is then $1,000,000,095. If that money is divided equally among the 20 people, each gets $50,000,004.75. That amount is the average amount of money that the 20 people brought into the room. But the median amount is $5, since one may divide the group into two groups of 10 people each, and say that everyone in the first group brought in no more than $5, and each person in the second group brought in no less than $5. In a sense, the median is the amount that the typical person brought in. By contrast, the mean (or "average") is not at all typical, since nobody in the room brought in an amount approximating $50,000,004.75.
I certainly did not imply that. For me to have implied that, i would have had to state that the 17 Trulia users and you were financially representative of the trulia community as a whole. I did not do that.
I would then have had to give some subjective opinion as to what level of net worth defines some one as a "the word you used-Trulia profanity guidelines don't allow me to quote it" and what level is a "winner" I did not do that either. You have, though, and by your analysis, the break point is somewher north of $20,000.
Your post adds value to this thread because it points out that occasionally, people will make assumptions about averages and medians, percentage increases and decreases and all other kinds of numbers and statistics that are unsupported by what is known about those statistics.
