A Normal Bell Curve calculates a grading curve from a comparison of
student results. A Bell Curve will calculate grades based on the
amount of standard deviations from the mean average.
Note: A small test population with a minimal difference between
the highest score and the lowest score will not result in an
effective Bell Curve scale.
Using a Bell Curve, the population grades will break down as follows:
Example: In a true Bell Curve grading method, a test population of
100 students should have 2 students with a grade of "A",
14 students with a "B", a total of 68 with a "C", 14 with a "D"
and 2 with a grade of "F".
