I personally really liked Professor Tsiang, he seemed really relatable and always slipped in funny TV show references on tests and in lectures and instructions. He was genuinely caring towards students' well being, especially mental health. He stressed this multiple times throughout the quarter, gave us free points on quizzes and exams related to this, and extended deadlines when he felt the workload was too much. Additionally, no textbook was required and you get everything you need just from his lectures. They were generally shorter lectures too, the allotted time is normally 50 min a lecture but most of the time they were closer to 30-40 minutes. The labs were pretty straight forward, with the instructions basically telling you everything you need, so don't stress for people who haven't used R or coded before!
That being said, I did feel that there was a lot of work for this class, weekly quizzes, homework, and biweekly labs. It was manageable if you didn't leave things to the last minute however. I felt that the graders were a bit harsh, but still did well on most assignments. Prof Tsiang did require Campuswire participation, which you could also get EC through which I thought might be a nuisance at first, but was super easy and the majority of the class got most points for this. I would say try to get most of your points early on so you don't have to worry about it as much later on, but I checked Campuswire maybe three times a week and tried to answer or ask a question each time and achieved the extra credit level before week 8.
The exams were a bit harder, but you have plenty of time and open notes so I think just understanding concepts, and understanding the wording Professor emphasizes and keeping a diagram of the validity conditions is super helpful. He does not provide practice questions, so I reviewed the quizzes and did some from the suggested (but not required) textbook.

The practice midterms and exams are definitely not reflective of the actual midterm and final, which really threw me off since they were more difficult...almost ambiguously and confusingly difficult. Exams were hard and I get why Dr. Tsiang made it harder due to remote learning. Nothing can really prepare you for it since there's no "practice exams/midterms" for remote learning. Recorded lectures were long and he read from the slides but it was digestible and Dr. Tsiang just followed the textbook (that is not required!) I really appreciate Dr. Tsiang not mandating purchasing textbooks and materials for the course.

Aside from emails, the primary mode of correspondence for this quarter was a Discord server which I really didn't go on much except to clarify a few things that someone else already asked.

His love for Parks and Rec definitely permeates into the course, so if you're a fan, you'll appreciate the incorporation of the show into the work...if you're not, just nod and smile.

Labs are easy since the TA just uploads the video doing the lab step by step, question by question. No problems with that. Labs were probably the easiest thing to complete from this course.

This is a class many of y'all probably need to take, so just bite the bullet now and take it and hold on. Don't let go or fall off the wagon mid-quarter and don't let time slip away.

Look, I hear Stats 13 is the easiest pre-req for LS majors. I am usually an A student, and was expecting this class to be a breeze. But, due to online learning, Tsiang made his exams a lot harder than it was in person (he used past exams as 'practice tests' even though they were wayyyy easier than the actual exams.) Recorded lectures were pretty straight forward, and I thought that I was well-versed in the material. Fast forward to Exam 1, I got a 77% (class average was 78%) and I was shook. Most questions were short answers, so I got many partial credit, and only got 1 multiple choice answer wrong. For the final I got a 75% (have no idea what was the class average), but same deal. To be fair, the exams are open note that's why they are harder, but even then, I was surprised since I'd do very well on the homework. According to syllabus, I had an 85% in the class, but Tsiang adjusted the grading scale to fit distributions, so I ended up with an A-. I am not too upset, since I was expecting a B, but I wish I would have been prepared on how detailed I needed to be when it came to short answer questions. Also he bombarded us with lecture videos Week 5, and it was just a bit too fast-paced and it was frustrating. I had many peers feel the same way as well. But at the end of the day, I really liked Tsiang, he's a good professor and cares about his students, I just didn't have that much interaction with him due to chaotic home life and to be honest, laziness to attend office hours.

I really enjoyed taking this class with Tsiang. He explains all the material very clearly and puts in a lot of effort into teaching. Stats is not the most interesting subject (at least to me) but he makes his lectures as engaging as possible. He was also super helpful during office hours and was willing to spend lots of time with students to make sure they understand a concept. In addition, his exams were completely fair and by no means challenging as long as you put in a little bit of effort into studying. He even let us use a cheat sheet which was really helpful.
If you're hesitant about taking this class with Tsiang because of the reviews - don't be! I don't understand why people are upset with his teaching. I thought he went above and beyond to help students and is in general a super nice person. Would definitely recommend this class with him.

I put off taking stats for as long as I could during my UCLA career just because I had no interest in the material. Nevertheless, I tried to go in with an open mind. Unfortunately, Tsiang did not help this situation. For 2 hours, you basically sit and listen to him read from slides verbatim. It was borderline painful some mornings. Again, maybe this is because I just didn't find the material interesting or maybe it was just presented in a really boring way. In terms of the class, the tests are all multiple choice and you get a cheat sheet, but they are still pretty tricky. Best advice is to look at the conceptual multiple choice from the textbook chapters (he steals questions from here). There are twice weekly discussions, but in one per week the TAs go over the weekly labs and basically give you the answers which is nice. The other discussion per week is spent going over example problems. Each week you have homework which definitely takes a while to complete and is graded on accuracy which is just annoying. Although he gives some extra credit opportunities, it is for a very low level (1% max of final grade). Lastly, I agree with the previous poster about the CampusWire arrogance. Although I think what he was trying to do was get students to think about the concepts and come up with the answers themselves, he does this in a very poor and rude manner. BUT he is super responsive on there which I guess is good. (Also, please stop the "ain't nobody got time for that" jokes... they are beyond cringe worthy after week 1).

Not sure who the hell is writing these reviews. Maybe this was an off summer for Tsiang, but the guy is not what he is made out to be by this bruinwalk page. People saying he's funny are saying that because every 30 or so minutes in his (painfully dull) 2 hour lectures, he says "aint nobody got time for that" and it wakes a portion of the class up. Maybe that is enough for the kind of people who write bruinwalk reviews to consider him funny. See, I accidentally missed the course evaluation deadline, so now I have to settle for a bruinwalk review in the hopes that it finds whoever tracks the progress of junior lecturers. One positive for Tsiang is that he gives great life advice before tests. He reminds students that mental health, sleep, and overall well-being is far more important than any grade. I respect his thoughts on this. That being said, his tests were still tough and required a lot of preparation. Also, anybody who says he is a "nice guy" or teaches with "good clarity" is either tripping or had a different teacher. This guy is far and above the most condescending teacher I have ever experienced. Though it is hard to tell whether he is robot or human from lecture, when you actually meet with this guy in person, you quickly realize that the attitude he puts out on Campuswire is true to he actually is. Campuswire is an online forum and part of the class is participating on it by asking and answering questions. If you somehow find the patience to rack up 50 upvotes on your responses, you can earn a whopping .5% of extra credit. I swear to you, on every singly discussion topic you click, you can find a condescending response from Tsiang, shaming the person for asking, and completely dodging the task of actually answering the question posed. He manages to consistently leave you guessing in confusion, putting a roundabout bullshit response to any and everyone who dare ask for help on the website. Take this review as one angry review from a kid who you think got a bad grade, or take this as a collective effort by 12 csesh students who all got A's and B's, but were shocked by how misleading the teacher's bruinwalk page was. Tsiang - get over yourself, stop your Parks and Rec references and learn to teach.

Great professor and relatively easy class. The homework and lab are busy work but it isn't too much work, especially because some of the labs are bi-weekly. Tsiang is a great professor and if you love Parks n Rec, you have to take this class.

Tsiang was a great professor and made stats manageable. He really cares about his students and is super helpful. Midterm and final are multiple choice but a few of the questions were a little tricky. He allows cheat sheets though which are really useful. Homework can take awhile but he gives a lot of time between due dates, and the lowest grade is dropped. Labs were pretty easy, and the last one was extra credit. There are also weekly online quizzes of 5-9 questions which weren't too bad, and the lowest grade is dropped. Discussion is twice a week but weren't mandatory and counted towards extra credit. Tsiang was pretty funny and tried to make the material engaging, but lectures were kinda boring just because it's stats and a lot of people stopped showing up to class

Not hard to pull an A because:
1) midterm+final not too hard
2) a good portion of your grade is assignments that you can check with TAs for accuracy if necessary
3) extra credit: up to 0.5% for Campuswire discussion, 0.5% for section/lab attendance (can miss up to 3 sessions), entirety of last lab
4) lowest grades in each portion of grade (quizzes, hw, lab) is dropped
5) no clickers/participation for lecture
6) unrelated to grading, but textbook isn't required though hw assignments refer to it. you can get by with pictures from friends or the pdf
7) some real homies on the Campuswire discussion forum (like Piazza but less ugly) pretty much give answers out to questions if you get stuck on assignments bless yall

Despite all this, I found it harder than a lot of the other LS major prereqs. Before you think poorly of me, this material is SO DRY my constantly chapped lips are like an oasis in comparison. First day of class, "new quarter new me" mentality in place, and I still fell asleep. It's really not Mike's fault that I found the course material boring-- he's a pretty funny guy and not uptight like some profs can be at times. Class attendance at lectures the few times I went was ABYSMAL because you can just watch it on 2x on Bruincast if you want (and still probably nod off while watching the video too).

Tsiang is an amazing professor! Take this class with him. The midterm and final are somewhat aggressive but he lets you use a sheet of paper for notes. Make friends and do the homework and labs together and they are not too bad. Here's the grade breakdown:
Homework- 16% (Lowest is dropped)
Online Quizzes- 16% (Lowest is dropped)
Labs- 18%
Midterm- 20% (Was 30 multiple choice)
Final- 30% (Was 40 multiple choice and he gave 2 extra credit questions)
