Realistic Prerequisites

  • Some background in probability and statistics. The course material was somewhat advanced, and it would be hard to develop a good understanding without prior background.
  • 18.02 (multivariable calculus).

Subject Matter

  • Very applicable if you’re involved in research. Covered statistical methods used to analyze data.
  • Presented in thoughtful manner, building on previous concepts.

Course Staff

  • AMAZING professor. Students found Jeremy kind, caring, available, passionate about the subject, genuine in his desire for students to succeed, etc.
  • TAs were approachable and knowledgeable.


  • Students learned the most from the problem sets and from the lecture notes, rather than from lectures.

Problem Sets

  • Roughly weekly. Covered the important topics from the week.
  • Greatly contributed to learning.
  • Occasionally required creativity.
  • Challenging and time-consuming but fair.


  • 6 quizzes. Students preferred the 6-quiz format to the normal exam format.
  • Quizzes were very fair, and course materials provided adequate preparation.


  • Lecture notes provided by professor were extremely comprehensive and useful. They were the main class resource.
  • The professor also provided pre-class readings and class practice problems, which students found helpful.


  • Grading was fair and transparent.
  • “I expect most people in this class to get As or Bs.”

Advice to Future Students

  1. “Advice: take the class if you have even a little interest in statistics”
  2. “Ensure that you have somewhat of a background in probability/statistics before taking 18.05.”
