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.

I took AP stats in high school, so I already knew the material, so the class was really easy. I only attended lectures because of the poll questions, which gave you 2% extra credit at the end of the class. The midterm was incredibly easy, but the final was hard. However, due to the protests and blm, he made the final optional and changed the weight of the tests. The homework was easy, especially since the TAs basically did the work for us. The weekly quizzes were also easy, and he gave us ample time to do them. The only part I hated about the class was the labs, I still don't understand why they are necessary to the class, but at least the TAs walk you through them step by step.

If you want an easy class with a chill professor take this class with Wu. The info isn't exciting, but Wu teaches in a clear way and cares that his students are learning. He also wants students to succeed, so he ended up dropping multiple quizzes, homeworks, etc. The TA walks you through all the labs and gives you answers to all the homework per Wu's instructions. Take this class and if you put in just a bit of effort, you will get an A.

It doesn't get better than Professor Wu. This guy is the nicest, most friendly teacher I've had. He was so accommodating with the whole COVID situation, but tbh he didn't even need to be. Stats 10 really isn't a hard class. You get notes during the tests and the quizzes weren't even timed. They are super fair when grading homework and labs and still drop your lowest grades. And seriously - Wu is the best.

The midterm and final were extremely hard. The average score for the final was a 32%. The tests seemed like they were designed to trick you and the problems were many steps and took a very long time. Nothing on the test was really conceptual and endless studying of the lecture slides were not enough because the questions are not big picture at all and rather very niche and expand on edge cases or details that were either never or hardly covered. There was no practice test and the test guide was very vague and often did not include material that was on the test. The homeworks, tests, and lecture examples were all extremely different so the learning of material was all over the place and never really solidified. The homework were very challenging although the TA pretty much went through every problem during discussion which were recorded. His coding was often incorrect however and it seemed like he didn't prep very well before the discussion. Overall, I would advise to take this class with another professor but I will say the curve is fair and the professor is very accommodating.

I took this class the summer of 2024 and it was a complete dumptster fire. Initially, about 40 people showed up to his lectures, but after quickly realizing that we were not learning anything, it dropped to about 6. Guani has a very dry, monotonous, and hard to follow along with teaching style. Additionally, his lectures focus heavily on theory which would not be an issue if that is what the homework and tests were about. HOWEVER, that is not the case as you will soon see.

The homeworks are very programming based, much of which you don't actually learn in class. There is much self learning to be done in this class as there hardly any resources provided to help you. Then we proceed to the worst part of the class. The tests. I believe the median of our midterm was a D, which means atleast half the people in our class failed it. Additionally, the highest score in our final was a 58 out of a 100, and the median was like a 35. So literally every single person in the class failed the final.

Both the midterm and final were on Lockdown browser and required an extremely strong knowledge of programming which was never taught in the course. You are only allowed one sheet of scratch paper front and back which can only contain formulas, not examples, so you can't just fill it up with code. Obviously with this much fuckery and poorly planned test taking where we did not have anywhere near enough time to take the tests, it ended with bad grades.

He is also going completely off the rails by not following the traditional grading distribution and just giving everyone shit grades, including my friends who scored in the top 20 - 25 % of the class.

Please avoid this sorry excuse of a professor at all costs. You won't learn anything and your GPA will get fucked.
