You make good points. WS and I were having an earlier conversation regarding education. So much of the education system debate is politicized it's hard to get good info.

Hi Neocon, << First, a variance of 3 percent is statistically insignificant, rather than "morally significant". >> I agree it is difficult to know what to make of these results, but you cannot say even that 3% is statistically insignificant.....or significant. It depends on the nature of the distribution of test scores and the relationship with the distribution of the underlying trait. For example, if the standard error were 0.5%, then a 3% difference would be a highly significant change. In large standardized tests the standard errors tend to be rather small, but because this information is not given and no statistical analysis offered, all bets are off. But overall, I'd say our public school system has gone from bad to worse over any considerable period of time. The level of educational achievement in any absolute (or even relative) sense has steadily declined, and has for a long time been unacceptably low. And that is "morally significant." JMVHO...... YMMV WS
