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 |
|---|---|---|---|---|---|
| HONDA, KO | 3.17 | 3.16 | 51 | 2 | 53% |
| HIGGINS, VIJAY | 3.26 | 3.29 | 34 | 1 | 62% |
| VICARIA ANGEL, MARIANA | 3.13 | 3.10 | 29 | 1 | 48% |
“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.
