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.

Dec 22, 2008· I came upon this site while researching grading curves for a friend in law school. My education was years ago when 93 was an A, 86 a B and so on. Grading on the curve was done only when everyone passed. It was then necessary to curve to assign a percentage A and an equal percentage as F with the various grades falling in between.

In a system of pure curve grading, the number of students who will receive each grade is already determined at the beginning of a course. Other forms of "curved" grading vary, but one of the most common is to add to all students' absolute scores the difference between the top student's score and the maximum possible score.

A bell curve (also known as normal distribution curve) is a way to plot and analyze data that looks like a bell curve. In the bell curve, the highest point is the one that has the highest probability of occurring, and the probability of occurrences goes down on either side of the curve.

The "curve" referred to in the term is the "bell curve," which is used in statistics to show the normal distribution—what the expected variation is—of any set of data.It's called a bell curve because once the data is plotted on a graph, the line created usually forms the shape of a bell or hill. In a normal distribution, most of the data will be near the middle, or the mean, with very few ...

If the highest percentage grade in the class was 88%, the difference is 12%. You can add 12 percentage points to each student's test score. If the test is worth 50 points and the highest score is 48 points, the difference is 2 points. You can add 2 points to each student's test score.
