I'm a STEM major and I LOVE math but oh my god do not take this class with this professor. We were supposed to cover 10 units in the course and only covered 2. ONLY 2!!!!!!!!! His lectures were all over the place and half the time when students asked questions, he didn't know how to answer them and this is a BASIC STATS INTRO CLASS. He was not an accommodating professor at all and for being someone who has gotten A's my whole life alongside my friends who were in this class, we all got C's because he asked questions on the midterm and final that we never covered in class. I even emailed him after the final and questioned if he would curve the score because everyone got a C or below and he said he wouldn't do so even though we got tested on units we were never taught. I feel bad for stats students who needed to learn the rest of the 8 units to prep for their next stats class since we only covered 2 units. I literally am so infuriated by this professor and the fact that he never apologized to us once for not doing his job and we were the ones on the back burner. Exams were on respondus with a separate camera watching our hands. The questions were very conceptual so even if you have good stats knowledge the questions are tricky, especially when you're being tested on topics that you weren't even taught how to do. Please please please go with any other professor.

Wu was nice, but not a very good professor. His lectures were often not very clear or easy to follow and I ended up having to learn most of the material from the textbook. That being said, the class itself isn't very difficult, and an A is definitely possible if you do the work.

Dr. Wu is very generous with the grading (quizzes are only based on completion, assignments deadlines can be extended for up to two weeks,...). His office hour is great, and he is willing to stay a long time after to help you with the assignments. The curve of the class is also fantastic (I certainly would not get B if not for the generous curve). However, the midterm and finals can be very rough where he asks minor details questions during lecture, so be very well-prepared! Overall, Dr. Wu is very kind and understanding and I certainly would want to take classes with him again.

The grading in this class consisted of weekly homework, a midterm, final and a weekly quiz. I'd say the material/class was more difficult than I expected, especially homework assignments. But at the same time, Wu was aware when he made things too difficult and made accommodations like extending homework due dates, giving hints and canceling quizzes when necessary. He accommodated students with the covid-19 epidemic by heavily curving the final since I did not deserve the grade I got in the class, to be honest.

Overall, with the clear lectures and challenging but fair material I'd recommend Wu for this class if you did well in stats 20 and remember lots of R coding from then. Otherwise it might be tough.

Professor Wu is a really good professor, if you keep up/go to lectures regularly (I took this in Spring so due to COVID he would just upload the lectures so the class could be asynchronous) you will be fine. He tries to help students and the final was made optional for the class as he didn't want to provide additional stress during the protests. He really cares about his students and I think his lectures are quite clear. I didn't buy the textbook so I wouldn't say it is essential as the TA's usually went over the problems in class. Labs were also explained step by step during discussion so discussions are definitely useful. Overall, this class is very manageable and Professor Wu tries to make it as engaging as possible. He also offered clicker points for lecture participation as extra credit so he tried to really help. During the midterm you are allowed one double-sided cheat sheet so its manageable to do well on the exams as well. I would really only say that the quizzes were sometimes very ambiguous and could potentially be difficult but you get to drop your lowest quiz and homework anyway. I would definitely recommend taking it with Professor Wu if you can!

Stats 10 is generally an easy class and Wu is a pretty good prof to take it with. His lectures aren't the most engaging because his voice is monotonous, but he really paid attention to the chat and always answered our questions. His lectures are on slides, which he posts on CCLE. He does clicker/poll questions during lectures for participation EC (up to 2%). Quizzes, the midterm, and the final were all multiple choice. Before both exams, he posted a study guide and gave us a practice test. During discussions, TAs basically do the lab with you and they go over homework questions. For this quarter, Wu made the final optional, dropped our lowest 2 grades from homework and quizzes, and cancelled our last lab, so he's really accommodating and willing to empathize with students.
