  Additionally, a number of behavioral statistical procedures are based on the assumption that scores are normally distributed; for example, t-tests and ANOVAs. Bell curve grading assigns relative grades based on a normal distribution of scores.

• Normal Distribution of mean height of males: probability

• As a teacher do you feel that grading curves are fair? Does it just explode the true aptitude level of students or, does it allow for a particularly unfair test to seem more fair?As a teacher do you feel that grading curves are fair? Does it just explode the true aptitude level of students or, does it allow for a particularly unfair test to seem more fair?

  A bell curve cannot explode the aptitude level of the students, as that seems to imply that it bumps up all students grades, however, a true curve can not do that, since some students must fail.
