Damn, I thought my classes of over a hundred were big...1200?Admittedly, with this being my first semester at a school that curves its science classes, I know nothing about curves. If out of 1200 students the class average is in the mid 60's, is it possible to predict where a A will fall?
Hey, now all you have to do is teach just about everyone on this forum how to normalize functions, and you've answered the question.Yes,
Take the function f(x)=and normalize. Normalize so that the average occurs at the maximum and the top %10 recieve A's. It should be 88%+
Yeah, depends on how tightly packed in everyone is (see: standard deviation). If 60% of the class is between 50-70, then don't be surprised if an 80 (or even lower) would be an A. If it's more spread out (i.e. 40-80) then an A will be higher.85-90 will be the bottom or an A-, depending on the grading system. Then again, I once had a class where an A+ was a 90, so it just depends.
