Grades
3.55
Average grade awarded in STATS 100A. Not a student rating: this is what
the grades were.
The mean of every letter grade the registrar has published for this course, pooled across every instructor who has taught it. It is not shrunk toward anything, because a course average cannot be pulled toward itself. Standard error 0.013.
In the A range
The share who got an A minus or better: A+, A or A minus, out of every letter grade awarded in this course. Pass/no pass outcomes are counted separately and are not in this figure.
67%
of the 2,470 letter grades
D, F or W
The share who finished with a D or an F, or withdrew. The closest thing here to a difficulty signal: it counts the people the course went badly for, which an average grade hides. Pass/no pass and S/U outcomes are counted separately and are not in this figure, so a no-pass is not in it either.
2.1%
of every letter grade awarded, plus withdrawals
Taken pass/no pass
The share who took this pass/no pass rather than for a letter grade. A high number usually means it is popular as a GE with people protecting an average. These students are excluded from the figure at the top of this block.

›iWhat 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 15 terms ran 2.97 to 3.99.

Percentages are of the 212 letter grades. Grey bars are non-letter outcomes: passes (P) and incompletes (I).
›iHow 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
Predicted GPA, raw average, sample size, terms, A range and the workload reviewers
reported for every instructor with a grade record in this course
“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.
The chain dibs can see is 4 courses long before STATS 100A. This is a floor, not a deadline: dibs has not read a class page for 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 Falls
Ran in 5 of the last 5 Falls.
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.

Sections in Fall 2026
You enroll in the discussion, not the lecture, so a discussion's status is the one that decides whether you get in. A lecture can read open while every discussion under it is full.

Student reviews
What taking STATS 100A was like: the work, the teaching, and what students wish they’d known.
No student reviews are available to read on dibs for this course yet. Took it? Tell the next person what helped, what was hard, and how you spent your time.

External reviews are separate and do not count toward the dibs rating.
How each lecture has filled since dibs first saw it.
This course runs 4 lectures; the legend under the chart picks one.
A dot is a reading where something moved: the seat count, the status, or the waitlist.
›iWhat 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.

That check recorded no change; changes between checks may be missed. For 5 hours dibs was keeping a record and did not reach this section. Nothing before 24 September at 15:00, where this section's record starts, has a read either way, which is 885 hours of this window. Where the drawing is faint or broken, that never means the readings are doubtful. It means the stretch between them is unaccounted for.

›iHow 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.
