The registrar's own records: 1 grades over 4 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.
What is inside that record
No summer session is in that record.
The table below splits them.
Historical grades for LEW, VIVIAN, across recorded terms. The course summary above includes all professors.
- A 1 · 100.0%
- IP 289 of 290
Percentages are of the 1 letter grades. Grey bars are non-letter outcomes: in progress (IP).
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.
By instructor

|---|---|---|---|---|---|---|---|
| LEW, VIVIAN reviews ↗ | 3.62 | 4.00 | 1 · | 4 | 100% | very light | Closed by the department |
| ZES, DAVID ANTHONY reviews ↗ | - | - | 2 | - | - | Closed by the department |
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 6 courses long before STATS 140XP. Read from Fall 2026, because dibs has not read a class page for STATS 140XP in Winter 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, MATH 3B, and STATS 101B, 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 Winters
Ran in 2 of the last 4 Winters, so it turns up in Winter sometimes rather than dependably. dibs has no record of it in any quarter since Winter 2023.
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.
From the registrar's catalog
(Formerly numbered 140SL.) Lecture, one hour; discussion, two hours. Enforced requisites: courses 100B, 101B. Limited to seniors. Opportunity to solve real data analysis problems for real community-based or campus-based clients. Students work in small groups with faculty member and client to frame client’s question in statistical terms, create statistical model, analyze data, and report results. Weekly meetings in classroom setting to study basic consulting skills, share experiences, exchange ideas, and make reports. On-site visits as necessary. Courses 140XP and 141XP must be taken in consecutive terms. In Progress grading (credit to be given only on completion of course 141XP).

Final enrollment, averaged across each term's sections: between 28 and 43 a term over 4 terms, summer excluded, most recently 43 in Winter 2023. That is the shape across years, not this term, which is above.
From the people who took it
Student reviews
What taking STATS 140XP was like: the work, the teaching, and what students wish they’d known.
Your experience could be the first.

External reviews are separate and do not count toward the dibs rating.
Seats over time in Winter 2026
How each lecture has filled since dibs first saw it. This course runs 3 lectures; the legend under the chart picks one.
A dot is a reading where something moved: the seat count, the status, or the waitlist.
What a flat run means, and where a line starts
Flat between dots means it did not drift, it held and then jumped, and a line starts when dibs first saw that lecture rather than reaching back before it existed. A lecture that has never moved draws a flat line across the whole window, and one with two or three readings draws a line joining them, which is too few to read a trend from.

How readings and alerts work
A reading and an hourly record are different things, and most charts here hold more of the second missing than present. dibs has taken readings of a section since long before it began keeping an hour-by-hour log of when it looked, so the empty stretches are dibs saying it was not keeping that log yet, not that it looked and found nothing. That is the age of the record and not a fault.
Seat counts show the last successful read, not live availability. Refreshes can be delayed by request limits or upstream interruptions. Watched sections receive priority, but an hourly update for every section is not guaranteed.
The registrar can change a seat count between our checks. Alerts depend on dibs detecting an opening and completing delivery; a quiet watch does not prove that no seat opened. Check the registrar before enrolling.
