Cumulative Scores
Posted 6 May 2004 by herman

Here's a quick summary of exam and homework scores.

I've tried to put everything (except the final) into a table, as follows:

  pin   a   b   c  d  e  f  g  h  i     j   k  l
   --  -- --- --- -- -- -- -- -- -- ----- --- --

Column (a) is the midterm exam score, columns (b)-(i) are homework scores, with column (j) being the sum of all homework scores; then column (k) multiplies (j) by 0.673401 so that the highest total will be 100, which makes the weighted total have proper percentages (20% for midterm, 30% for final, 50% for homework). Column (l) then is the current weighted total --- everyone has "0" for the final in this table.

The distribution of scores from column (l) is shown in this graph: prefin.gif.
