### What is Stat 88?

Stat 88 is an introduction to the theoretical underpinnings of the methods used in Data 8. It is intended for students who have taken some calculus and

• are intending to major in areas that require a strong foundation in probability and mathematical statistics, or
• are intending to minor in data science and want to see how theory and practice can enhance each other.

Stat 88 will prepare students well for the probability and theoretical statistics that is covered in Data 100 and Stat 131A.

### What requirements does Stat 88 satisfy?

• Along with Data 8, Stat 88 satisfies the Statistics requirement for the Economics and Business Administration majors.
• Stat 88 satisfies the Probability requirement for the Data Science minor.

### Who can take Stat 88?

Stat 88 is restricted to students who:

• Have not taken Stat 134, 140, 135, or 102; no credit will be given for Stat 88 after these courses.
• Have taken one semester of calculus at the level of Math 16A, Math 10A, or Math 1A.
• Have taken or are currently taking Data 8 (CS/STAT/INFO C8)

All of the requirements are enforced because the course has been designed specifically for students who have the above background in math, programming, and statistical inference.

### What is the best way to succeed in Stat 88?

• Participate in lecture and discussion sections. Yes, really. The course staff does its best to create effective, efficient, and enjoyable sessions for students to learn.
• Read the textbook or your lecture notes, and go over the problems done in section, before attempting the homework. Yes, really. You should not expect to simply remember everything from lecture and section, especially after the first couple of weeks. If you have time, do the remaining problems in the textbook.
• Make a serious attempt at exercises by yourself before you seek help. Yes, really. The only way to become an independent problem solver (and, incidentally, to succeed in exams) is to try to solve problems independently. Your goal should be to increase the fraction of work you do by yourself, as the semester progresses.
• Study concepts, not formulas. Don’t scroll fast through the words in the textbook and only stop when you spot a formula. Yes, really. Learn how ideas fit together; don’t memorize solutions to exercises. Problems in exams (and in your next class or research or job) won’t fit neatly into boxes that you have seen before.
• Use Piazza, go to office hours, make friends with whom you can study. But if you have friends who always seem to know how to do the problems while you don’t, thank them nicely and then ask them to go away. Yes, really. Staff will be happy to help you figure out the best way for you to begin to take charge of the material.
