Sorry don't mean to belabor this point but I think "standard distribution" (changed from standard deviation) is still incorrect. "Standard" referers to standardized parameters (i.e. mean, variance) as in "standard normal" which has a mean of zero and variance of one (and standard deviation of one). Certainly not the case here. Maybe you mean "bivariate normal with positive correlation"? http://en.wikipedia.org/wiki/Multivariate_normal_distribution http://en.wikipedia.org/wiki/Multivariate_normal_distributio... Interesting thing is the (positive) means and variance seem similar which is consistent with underlying random variable being the same.

Yes, you are right. I wasn't being especially rigorous, and technically correct is the "best kind" of correct. :)

  No worries. Statistics can be very confusing. Part of the reason it is so confusing is all the sloppy usage we come across in the media and on the internet. Everyone wants to use statistics as a tool to bolster their point of view but don't want to bother to actually learn enough statistics to deal with the situation they are trying to analyze.
