Shi is extremely inconsiderate and not understanding as a professor to say the least. She almost never respond to emails even with those emails addressing grading questions (she gives a one-week window for any questions related to grading and does not respond for a week, which is ridiculous). During this quarter there were still covid-related issues and concerns, Shi refused to record any live lectures even when most of the other classes still did.

I am very grateful to have had Professor Shi for Stats 101B. She is very kind and always willing to answer questions at the end of every lecture. She also made accommodations for the class because of the ongoing protests and coronavirus pandemic by offering multiple lenient grading schemes, so you'd pass the class with a P (or C at worst), unless you absolutely bombed the homework assignments and midterm. This was also her first quarter at UCLA as a professor, so hopefully the stats department retains her.

The workload of this class is very manageable. There were 6 homework assignments (the one with the lowest score is dropped) and none of them were more than 3-4 problems. They were very similar to the examples in lecture slides and as long as you followed her code examples you'd be fine. The midterm was fair, but you just had to be very careful with the wording of the questions. The final was similar in difficulty too. Both exams were primarily multiple choice and some fill-in-the-blank questions.

If you took 100B and/or 100C, most of the beginning topics will mostly be review since you start out with basic ANOVA and hypothesis tests. However, the second half of the course can be kind of overwhelming at times when you're dealing with multiple factors and all the interaction effects.

Overall, I would recommend taking this class with her! I'm not sure how the in-person version of this class will be but it is worth taking if she's teaching.

Took Stats 101A with Shi. 2021 Winter, remotely

Good: few homework, less content each lecture, take-home exam(24hours)

Bad: she is late more than 5 minutes EACH lecture, harsh grader, no reply email, no argument of Grade, the whole quarter content can be learned 5 weeks. I learn much more from TA. Quiz is tricky each week and easy to miss.

Lectures are on the unclear side (this was her first quarter teaching) but overall she is very kind, helpful and a pretty unintentionally funny person (she would giggle a lot when asked questions which I thought was really funny lol). Didn't put in much effort in the class so I ended up P/NP, final was really difficult but midterm was decent and homeworks were light and easy and spread out so she def didn't overload in terms of workload. Overall would really recommend she provides a lot of help when needed and I did learn a decent amount!

Note: This review is from Spring 2020, which was conducted entirely remotely due to the COVID-19 pandemic.

Professor Shi taught this course relatively well considering the circumstances. She was able to adapt as the quarter progressed, slowing down the pacing of the lectures to accommodate the students and ensure greater understanding. The lectures were straightforward and recorded so that they could be watched at a later time, should one choose to do so. Furthermore, she updated her lecture slides with clean, typed, and formalized notes after the completion of each lecture; these slides were more than sufficient in terms of relating the material learned.

With respect to the assignments and exams, there was a slight discrepancy, but nothing too egregious. The homework assignments were pretty straightforward but could be mind-numbing at times because of the monotony of plugging in code. The later assignments seemed to be less code and more analytical, but it was still a tad tedious. The tests, both the midterm and the final, were open-book but difficult nonetheless. Despite all of this, I feel as if they truly helped us gauge our understanding of the course material. With respect to the final grade, my friends told me that she curved rather generously after looking at the distribution.

TL;DR: Professor Shi gives straightforward, easy-to-follow lecture notes that help teach the material while also adapting the pacing to meet the needs of the students over the course of the quarter.

The coursework includes two exams (30% of your grade each, Exam 1 is like a midterm and Exam 2 is like a Week 10 final), weekly quizzes (20%, lowest grade dropped, no quizzes on exam weeks), and 6-7 homework assignments (20%, best 5 assignments counted towards grade).

Initially, the exams were scheduled to take place during lecture, but Professor Shi was very accommodating and later changed them to be 48-hour exams. The homework assignments only contained a few questions each and were straightforward. The quizzes were also pretty easy and only tested the important concepts, so it's a good, low-stakes way to see which areas you need to brush up on. The exams were more challenging and time-consuming than the homework but still very doable and fair. Lectures were quite dry and sometimes not that clear but maybe that's just me having a short attention span.

Overall I really liked this class for being very straightforward and having a manageable workload and would recommend Professor Shi for 101A!

Disclaimer: Online Class.
This is an easy class if you put down most of the "important sentences" from Professor Shi. Those are all crucial and helpful explanations to the core concepts that are otherwise not necessarily thoroughly explained in her lecture notes--even though they are already pretty detailed.
HW is easy. Exams(24 hours) and quizzes (timed) emphasize the details about equations and understanding of concepts.

Professor Shi is a nice professor. Her lectures are clear and structured, with detailed PPT and thorough explanations. Also, she is nice and considerate as she changed the syllabus to give us take-home 24 midterm and final. Her homework and tests are very fair as long as you pay attention to her classes and have enough practice. The small problem is that her pace in lectures is slightly slow, which can make you sleepy if you attend lectures in the afternoon. Overall, I recommend taking her classes.

I did not take 100B when I take this class.
Once I asked her a question in the quiz, she answered me “You will learn in 100B”.
The content of this course is not difficult. But her teaching has increased the difficulty. Many principles and details are not explained well. For me, textbooks are more useful than lectures
I prefer to email her to ask questions. She responds to the questions in the email more effectively than the office hour.
Although she is not very good at teaching, her homework and exams are not difficult. I cannot say that this is good. I don't think I learned a lot.

We all know that Stats101B itself is pretty challenging. Basically, professor Chenlu gives decent summarized slides of the textbook, but still, I had to read the textbook for solid understanding. And basically, the homework wasn't that hard, but the midterm and final were very confusing and tricky. She curved a lot because the average scores were lower than 70%. Overall, I liked this class, and I loved her talking style.
