<p>BTW goodenoughparent, I think you made an error in saying that 25% of the freshman class at Vandy this year scored over 2330 on the SAT. I see where you got that, I think. You took the 75th percentile of each section and added them up. It doesn’t work like that because the same student may not be in the 75th percentile on each section. Simple if extreme example: Student 1 gets CR=400, M=800, W=500 total=1700 Student 2 has CR=700, M=500, W=750 total=1950 So the 50th percentile for this very limited student body is CR=700 M=800 W=750. Add those up and you get 2250, but the actual 50th percentile for the total is 1950. Again, extreme numbers and the reality at Vandy or any school is not going to be that large, but it could easily be 100 points less. Or not. There is no way to tell from that data. Do you have another source that says the actual 75th percentile for the total scores is 2330? Because since it is virtually impossible that the same 25% of students scored in the 75th percentile on all three sections, it is similarly impossible that the 75th percentile for the total is equal to the sum of the individual tests.</p>
