grading bell curve

Posted by Bill on November 17, 2000 7:59 PM
I'm sure that this is a newbie question, but I can't do it! How do I take my students grades and convert them into 1. how many in each grade category (A,B+,B, etc.) and then turn that into a bell curve. I was able to do it, but with a ridiculous number of columns.

Try the NORMDIST function, which returns the normal cumulative distribution for the specified mean and standard deviation

paste the grades in the C column and use the following formula in the D column.


The A, B+, B, C+,..... grades can be generated using the following equation in the E column.

obviously the grade limits in the last equation can be adjusted to your own needs.
