- Statistics is used in almost any technical field.
- In CS in particular, statistics is central to the fastest-growing specialities, such as Big Data, machine learning etc.

- This is a
**MATH**course. - Even the programming problems (Homework, Quizzes) are actually "math problems in disguise."
- The course makes heavy use of calculus and
**LINEAR ALGEBRA**. - This is NOT a "formula plugging" course, nor does it consist of learning patterns to mimic. Every problem is different.
- Most students do well in the first 1/3 of the course, which involves only discrete probability.
- The second 1/3 of the course uses calculus, and the last 1/3 uses linear algebra. Students with a good intuitive understanding of those subjects thrive, while some others find the material quite difficult.
- Contrary to what you might guess (say, based on high school AP Statistics), the most challenging part of the course is the last 1/3, involving statistics. Good math intuition is crucial here.
- If you did well in calculus word problems ("Water is flowing into a conical tank...accelerating at a rate of...with leakage rate of..."), you should do well in this course.

- Similar to STA 131AB, but with CS applications and programming.

- No midterms or final. (Group project in lieu of final.)
- Quizzes are given in discussion section
**EVERY WEEK**. - There is a special Quiz on the last day of lecture.
- Quiz problems will often refer to specific pages in the
book. (Open book Quizzes.)
It is
**REQUIRED**that you read the textbook, in complete detail. Plan on**SEVERAL HOURS**of dense reading per week! - Quiz scores tend to be low, but letter grades are generous.
- Quiz 5 and Quiz 6 of Fall 2013 are typical in content and style. In each case, 40/100 was the cutoff for a B-.
- Quizzes form 60% of your course grade.

- 4-5 assignments during the quarter.
- Homework is done in
**GROUPS**. - Grading is done
**INTERACTIVELY**. - TA will ask each members of the Group questions, both about the assignment and about the course material in general. Each Group member receives a separate grade.
- Homework counts 40% of your course grade.

- The textbook is open source, i.e. FREE.
- It is downloadable from the Web, and you must print it yourself at a copying shop of your choice.
- You must have your own (not shared)
**HARD COPY**of the entire textbook, and bring it to all Lectures and Quizzes. - The textbook is not ready yet, as I'm still revising. See approximate version here.

- It is expected that the student be
**NON-PASSIVE**in learning. Most of the student learning comes from reading the textbook in very careful detail. - I used to lecture in the traditional way -- I spend time writing on the board, you spend time copying it to paper.
- Then I realized, "What a colossal waste!" So, now
**I give you**the printed notes, so you and I can spend the time discussing the material. - So, in lecture, we DISCUSS the book. I almost never write on the board, nor do I have Powerpoint slides.
- It is NOT recommended that students read the book ahead of
the lecture. In the lecture,
**I prepare you to do the reading.** - Goals of the lecture:
- Clarify issues brought up by students concerning reading related to the last lecture.
- Prepare students for the next reading material, by giving an overview of what the material will do, and going into the more difficult examples in detail .
