Many educators feel their grades should fit a normal distribution and often apply curves to make them fit one. One way to do this is to convert numeric grades to z scores using the mean and standard deviation for the grades, then use an equation such as "newgrade = 70 + (z * 13)". Do you think grades should fit a normal curve? If you were a teacher, would you use one?
