The registrar's own records: 1,385 grades over 17 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.
What is inside that record
4 of those terms are summer sessions, and summer sessions are counted here.
The table below splits them, and term averages across those 17 terms ran 2.96 to 3.73.
Historical grades for all professors, across recorded terms. The course summary above includes all professors.
- A+ 62 · 4.5%
- A 296 · 21.4%
- A- 244 · 17.6%
- B+ 302 · 21.8%
- B 195 · 14.1%
- B- 103 · 7.4%
- C+ 82 · 5.9%
- C 55 · 4.0%
- C- 23 · 1.7%
- D+ 6 · 0.4%
- D 1 · 0.1%
- D- 1 · 0.1%
- F 15 · 1.1%
- P 9 of 1,398
- I 4 of 1,398
Percentages are of the 1,385 letter grades. Grey bars are non-letter outcomes: passes (P) and incompletes (I).
How the non-letter outcomes are counted
They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication.

| MADRID PADILLA, OSCAR HERNAN reviews ↗ | 3.18 | 3.17 | 343 | 4 | 35% | - | not teaching it |

Why Predicted is not the Raw average
“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.
Grade records describe outcomes. For what a course is like to take, read student reviews written on dibs below or follow the separate external review link.
Workload and assignments
Work types reported in BruinWalk reviews of this course, across recorded instructors and terms. They may differ from this term's syllabus.
dibs has not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.
What comes first
The chain dibs can see is 5 courses long before STATS 100B. Read from Fall 2026, because dibs has not read a class page for STATS 100B in Spring 2026 and a department can change what it requires. This is a floor, not a deadline: dibs has not read a class page for MATH 170A and MATH 3B, so the real chain can only be longer than this, never shorter.
Counted in courses rather than quarters: dibs does not know which of them a department lets you take together.
In Springs
Ran in 4 of the last 4 Springs.
From the terms dibs holds, which start in Fall 2021 and exclude summer. A department can run a course in a quarter it never has before.

Lecture, three hours; discussion, one hour. Requisite: course 100A or Mathematics 170A or 170E. Survey sampling, estimation, testing, data summary, one- and two-sample problems. P/NP or letter grading.
