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 |
|---|---|---|---|---|---|
| LIU, KEFENG | 3.69 | 3.68 | 51 | 2 | 80% |
| HONDA, KO | 3.70 | 3.69 | 24 | 1 | 88% |
| PETERSEN, PETER | 3.90 | 4.00 | 24 | 1 | 100% |
“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.
