Walls average is much better.  You have bottom kids getting 1100 which is not great and mediocre.  But at least you have kids at the top 1/4 getting 1400 plus which is not happening at Banneker at all.  Maybe an outlier here or there but nothing of significant numbers.

How are you concluding that the "top 1/4" at Without Walls get 1400 plus and that the "bottom kids" get 1100? Nothing in the link you provided shows that. For all we know, the top performers at Banneker and Without Walls get the same SAT scores.

In any event, the gap in the average between the two schools has steadily decreased in recent years and presumably will continue to decrease.

This is basic math.  The kids at both schools are not getting the same SAT scores when there is a big 200 point spread difference.

You don’t know exact numbers but above are averages which means many get this score and then you have some above and below the average.  So if Walls has a 1300 average then it’s possible that 50% kids get this, 25% lower and 25% higher and there is your bell shape curve.  Percentages may not be accurate but the gist is your bell shape curve.

There is not a significant number of students at Banneker getting high SAT scores of 1400 plus if the average is only 1100.  It is nit possible because if there was, then the average would be higher.

Walls average is 1300 so yes, statistically there is a cohort getting higher than the average with 1400 plus[/quote]

Also to add that there is no big group at Walls getting below 1100 because if there was, this would drive your average of 1300 down.  Maybe an outlier few kids but not a big cohort if Walls average is 1300.  It is not statistically possible.  If there was in reality a big cohort below 1100, then that would tell you there is also a big cohort getting 1500 plus to get an average of 1300.[/quote]
