Stats 117: Introduction to Probability

John Duchi, Stanford University, Autumn 2026

Lectures

Tutorials and Sections

This quarter, we will be evaluating two modes of instruction beyond the standard lectures, which we term tutorials and sections. Sections will be similar to those in which you've likely participated in the past: a TA will lead either through a problem solving session or a concept session. We will take attendance in these sections, so please do attend the section to which you have been assigned. The tutorials are a new (and old, as they've been doing them in England for a few hundred years) idea that we will be testing, and will involve going through homework material in nearly 1-on-1 interactions with the TAs. We will randomize students into tutorials and sections during the first week of class; we emphasize that the assignment into tutorial or section will be completely random: precisely half the class will participate in tutorials, and half in sections.

For fairness, because we are evaluating these different modes of instruction, each subset of the class will be graded on its own curve: students attending sections in one curve, and students in tutorials on another, to balance the grade distribution.

Sections

Each section will be either a problem solving section, where you work through solving problems related to the course material together, or a concept section, which will be a bit higher level.

Announcements

  • Our exam will be Monday, December 7, 3:30 - 6:30 PM. The location is TBD, and you may bring 2 (and only 2) sheets of paper as cheat-sheets, double-sided.

  • If you are on the waitlist for the course, just be patient. We will (most likely) clear it at some point soon.
