Basically most incoming freshman from this school have scored at least a 1400 and that a quarter of their incoming freshman have scored a 1570 or higher. The 80th percentile return is 1172 percent. Calculation of quartiles quintiles and deciles is now straightforward after knowing how to calculate a percentile.

First second and third quartiles refer to the 25th 50th and 75th percentile respectively.
