trex,
Thanks for this great explanation, makes perfect sense. I better take a statistics refresher course! It also vividly points out the inherent flaws in using Median.

It seems the Case-Shiller index for SD is about the best we have at this point in time to get a more accurate read on the true underlying price action. With Median per Sq. Ft. being 2nd best (as Rich has so well pointed out). Unfortunately Case-Shiller seems to be about 2 months behind the others. BTW, does anyone know where you can look at charts of the various Case-Shiller indexes online?
