Hi Lovey,
As marks reduce, ranks increase rapidly. Suggested either an exponential function or a polynomial one. Got sufficient data by asking students to send me their marks and ranks – experimenting with the data found a reasonable fit with a formula as rank = ((k – marks) / n)^p.
Thus for 2010, rank = ((480 – marks) / 55)^5.5;
for 2011, rank = ((520 – marks) / 55)^5.5;
and for your year, 2012, rank = ((430 – marks) / 45)^5.5 worked very well (obviously, there is disparity between actual and calculated – more at the top level ranks).
Hope this information helps. Please feel free to revert. Click on the thumbs up or mark it...more
