grade curve
I'm thinking about curving the semester exam grades for my seniors. The average was 78. The highest grade was 90 (a B in this school division).
I'm not just going to add 10 to make it 100, then add 10 to everyone else's. No one is getting 100. No one got them all right.
So, does anyone know a formula for curving such as one something like this: multiply-by-divide-whatever-it-is-whatever-it-is-times-the-SQUARE ROOT of something?
