Reviews of professor Li Zou

Rating: 4.0/5, difficulty: 3.0/5
Really helpful professor.  Homework consists of a few textbook problems (some that're similar to lecture examples).  Exams and quizzes are a repeat of what's on the homework and shown in lecture.  Very lenient and helpful in office hours and open to questions during lecture.

Dr. Zou can be difficult to understand as he sometimes skims over explanations and the steps of solving ANOVA problems.  Then again, ANOVA is a difficult class to teach.  However, he's fairly lenient and accessible if you need help.  The homework, tests, and quizzes follow his lectures so remember to take notes in-class, read, and ask questions.

Attendance isn't mandatory which makes it easier if I can't make it to class. Homework is due in person so just keep an eye on the due dates. He's pretty understanding so I wouldn't stress too much if a personal issue comes up. Tests are open-book which makes them less stressful. PDF count too so I didn't need to spend any extra money

Thick accent, small writing, but that was honestly the worst of him. Generally a well rounded professor. We had HW bi-weekly and they were not THAT bad. Every exam we had was open everything, including having laptop and AI, and his grading is more on your approach than if you got it exactly correct. Concepts were hard, but not impossible.

Weekly assignments and few quizes and tests. He will write very small on the whiteboard so you will have to pull out your phone to see some of the notes. He isn't very harsh on grading though. He will give you most points if you follow the proper steps even though you don't get the correct answer.

Terrible class. This class is giving me so much pressure and depression. Avoid this professor

Professor Zou is one of the better profs in the stats dept. Although this was one of the harder classes, he's not a harsh grader- he's more interested in your approach to problems than answers. He's easily accessible outside of class, which is a rarity with most math/stats professors. Few quizzes, exams, weekly HW, pretty standard class structure.

Li Zou is a pretty decent professor. Very accommodating to covid as he records his lectures and is helpful if you can't make it to class or need to go back and see an example. Very lecture heavy so you do have to pay attention to what he is saying. One midterm but it was a take home exam and we had a week to complete it. Pretty decent choice.
