I love how, with a simple visualization, it’s immediately and completely obvious what is happening in the data.

To those who don’t get it: graders are bumping up students who are just below the 30% pass line. Essays are subjective so they have some grading flexibility.

I’ll never forget failing a class with 49% and then finding out a few weeks later that one of the other students (and likely many more) had been bumped up to 50% despite having an even lower grade.

The reason I failed? I wanted to learn the actual subject but the teacher had an agenda and was using all of the class time to show anti-racism videos so I complained to the principal. So how did she justify giving me 49%? Arbitrary grading criteria on essays. My mark went from an 86% at mid-term to a 49% by the end of the term as every single essay handed it was failed with no explanation other than she thought “I could do better.”

Now, I’m not opposed to anti-racism, but when it’s the focus of every single class in a class that has nothing to do with racism and I’m not learning the subject itself because we’re too busy watching anti-racism videos, that’s a problem. That was two decades ago and I still get annoyed when the subject comes up.

Err, as true as all of it may be, why did you have such a low grade? I understand her not bumping you up because she’s a bitch and you were a pain in her ass (rightfully so, sure), but why was your score so low that such a situation would be possible?

If you were smart enough to be aware of the problems with the teacher, why couldn’t you get a higher grade? Did she fail you on purpose or something, I mean I get you would never get a 100% on that class but why didn’t you have a 70 or 80?
