who has taken a statistics class is that it is obvious the sample is skewed. It is in no way a random sample. It is likely that the big holders (with the most to lose) signed up first and they will skew the results way high.
If it is not a random sample, there are no meaningful extrapolations to be made here. Do you know anyone who took a stats class? Lay the scenario out for them and tell me what they say.
Meaningful interpretation of statistical data is, by no definition, 2nd grade math. Anyone who thinks it is is woefully un-informed.
