Grey bars are non-letter outcomes — P/NP, S/U, incompletes. They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication.
By instructor
| Instructor | Predicted | Raw | n | Terms | A range |
|---|---|---|---|---|---|
| SOKOLICH, MARKO | 3.83 | 3.91 | 16 small sample | 1 | 100% |
| AHMADI, ELAHEH | 3.72 | 3.69 | 16 small sample | 1 | 75% |
“Predicted” is shrunk toward the course average, which is itself shrunk toward the department — so an instructor with a handful of students sits near the course mean rather than topping the list.
