UCSD 201a/b: Quantitative methods

This is the website for Psych 201a, 201b; they are presumed to be taken as a series with 201a in the fall, and 201b in the winter. This year 201a is also being offered as an advanced undergraduate course (Psych 193).

201a covers statistical graphics, probability, classical statistical methods, with an emphasis on the general linear model, and their implementation in R. 201b covers more advanced models and methods, including generalized linear models, multilevel/hierarchical regression, and computational approaches such as numerical optimization, Monte Carlo, and resampling.

Class meetings

Some class meetings are “lectures” others are “R labs”. Which is which will vary week to week. You will want a laptop with you for both types of class meetings.

Location:    1350 McGill Hall Times:    Tuesdays 2-4pm (undergrads: 2-3:20)    Wednesdays 5-7pm    Thursdays 2-4pm (undergrads: 2-3:20)

Undergrads: Homework (75%), Project (25%). Note: undergrads do not take midterm or final.

Grads: Homework (25%), Midterm (25%), Final (25%), Project (25%).


Homework: These are entirely in R, on our online system. It makes sense to seek help from other students when you get stuck, but make sure you do everything yourself, so that you will be able to do it on your own in exams, and more importantly, real life.

Exams: Midterm (in class) and Final (take home). Working together on exams is prohibited.

Group project: You will analyze some data, write a final report, and make a presentation. Details for 201a and 201b


  • Class mailing list: Sign up here
    Occasional announcements posted here.

  • Piazza: We try to answer questions on piazza, so that the whole class can see the question and answer, and we don’t have to reduplicate efforts. Find our class piazza here

  • Anonymous feedback form: here
    Please tell us how we are doing (lectures, labs, assignments, etc.) What are we doing well? What can we do better? What are we are spending too much or too little time on? What are you having trouble with? Etc.

  • Homework assignments: login
    Login is your ucsd username, password is full student ID, including letter.

  • Readings: Generally we will draw on a number of sources, and our own notes, as needed for whatever we are covering.
  • Software: We are using R and the Rstudio IDE.
  • Tutorials: In addition to various links from the schedule, here are a few general pointers:
    • is a nice interactive tutorial to learn basic R.
    • Datacamp offers great tutorials on R, etc. We have a complementary class membership.
    • Khan Academy has excellent brief lessons to help you recall high school math you may be rusty on (like exponents, logarithms, etc.)
