You may leave the list at any time by sending the commandDear Allstat listers. I have a question. Is there a way you can estimate the relative (%) loss that causes changing the basis over which the grade in an exam is calculated?Let me explain the case. One exam is based on 60 points. Suddenly one question is dropped due to complains of students (claming the question include topics not saw in class). The professor decides to eliminate the question (10 points) but then recalculates the grades on the new basis of 50 points.If you originally obtained any number of points in the dropped question I calculated (in Excel) that there is a loss in your final grade. If for example you got 50 points of 60 in the first calculation you get a grade of 83.3%, but then after elimination of that question in conflict you get 40 points of 50 posible, and your grade will become 80%.Is there a way to estimate (in general) what is the loss associated to this change (reducing from 60 to 50 points after elimination of one question)?Thanks for your time!
