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 |
|---|---|---|---|---|---|
| JIANG, HONG-WEN | 3.72 | 3.75 | 56 | 2 | 77% |
| GUTPERLE, MICHAEL | 3.57 | 3.55 | 46 | 1 | 61% |
| TSERKOVNYAK, YAROSLAV | 3.55 | 3.52 | 32 | 1 | 59% |
“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.
