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 |
|---|---|---|---|---|---|
| WOLLMAN, ROY | 3.98 | 4.00 | 64 | 2 | 100% |
| KOEHLER, CARLA MARIE | 3.97 | 4.00 | 23 | 1 | 100% |
| FEIGON, JULI F | 3.83 | 3.76 | 16 small sample | 1 | 81% |
“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.
