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 |
|---|---|---|---|---|---|
| TSIANG, MICHAEL | 3.70 | 3.70 | 1,449 | 10 | 77% |
| MAIERHOFER, THOMAS JOHANNES | 3.47 | 3.47 | 821 | 3 | 57% |
| ZHOU, QING | 3.42 | 3.41 | 300 | 2 | 54% |
| LEW, VIVIAN | 3.81 | 3.84 | 74 | 1 | 91% |
“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.
