[quote=Anonymous]OP again. Note that comparing Hardy %advanced today to Deal %advanced today does not fit with any of the claims I've made here. In fact, one of my main points in the initial post, underlined and separated out, was "Hardy, today, is pretty similar to Deal of six or seven years ago" In light of this, the percentage of advanced whites 8th graders at Deal 6-7 years ago were: Reading: 2006-2007: 72% 2007-2008: 59% 2008-2009: 67% At Hardy, the most recent data available show: Reading: 2009-2010: 70% 2010-2011: 50% 2011-2012: 42% For math, Deal: 2006-2007: 62% 2007-2008: 51% 2008-2009: 56% Hardy: 2009-2010: 60% 2010-2011: 50% 2011-2012: 42% Again, for the umpteenth time, the small samples sizes makes Hardy's number much more variable. The difference between 60% and 42% at Hardy is almost certainly not statistically significant; it is the result of random sampling error. [/quote]
