If a C is what the average should be, then the A's would all get normalized to a C.
- watwut 6y agoThe algorithm is supposed to be "simply asks for the student's grade divided by the average GPA at their school". Yours would put students at schools with other good students at disadvantage against those who go to less competitive schools. The assumption that students in different schools should have the same average is likely wrong.
- shard 6y agoIf you divide by the average score at the school, it assumes professors grade on an absolute scale that matches across universities, that a 4.0 is the same anywhere. Since this is not the case, then there already is built-in bias to the 4.0 at a certain school. At least if it is normalized to a C average, you'd know how a student stands compared to his classmates. You can then scale by the approximate academic rigor of the institution. If you don't remove the DC offset to the grade, then you would need to know both the individual's GPA along with the average GPA anyway to understand the number. This normalizing to a C average saves a step.
