The sample size is invalid, you cannot make a statistical analysis on 2500 player of 10,000,000. This is 0.025% of the player base, of which is only a subset who read this forum. Mind you the results are further skewed in that the "wealthiest" would need to do a good deal of research and are more likely to read several online articles and stumble across this poll. The standard deviation on such a small sample must be huge making this statistic irrelevant.Yes like any economic system, you will have a portion of the populace that rises above the rest through either hard work or luck. Once they get there they are able to compound their wealth by using their wealth, but please do not think a poll of 2500 players is at all a good cross section of the full populace.

Most political polls, which are designed to measure the opinions of hundreds of millions, only use a few thousand people as a sample size, so this study probably has a very large predictive value.You do have a point that the gathering of the data may be flawed based on who was more likely to answer the poll, but there's nothing wrong with the sample size.

"The sample size is invalid,"This former statistics TA would stamp an F on this statement, with good cause. 2500 people is a very good sample size for a wide variety of topics of study. The only time you need significantly larger numbers is when there is a very tiny difference between subjects, or if you are studying something (usually a vaccine for a disease) that has a very small chance of occurring. I would say that virtually all medical research that has ever been done has used way less than .025% of the human population, and sometimes the numbers for human trials of medications and treatments can be strikingly small. However, they are still valid and reliable sample sizes (as evidenced by the gazillions of drugs we now have in Western medicine).I like your point on standard deviation however. I would have liked to have seen a distribution chart (bell curve style) with the y-axis being the number of players and the x-axis being amount of gold. That's the one thing missing from that report IMO.
