I want to start off by saying I have never taken a stats class before, at first I was extremely nervous to take this class with this particular professor due to the amount of things the professor did to prevent cheating. Both exams were on respondus and we had to have our phones on zoom with the camera directed on our hands. As someone who already gets anxiety during exams, this policy did not really help ease it, I will say I was much more calm during the final though as I knew it was not as bad as i had initially thought. To break the class down, lecture attendance counted as extra credit (max 1%) and were recorded/uploaded to ccle, at first the professor would only leave the lectures up for 3 days and then we were not allowed to watch them, but for some reason he just removed this restriction after the midterm. Labs/HW were both worth 20% of our grades (so together 40%), the hw's were pretty easy, labs I hated simply because I did not understand the purpose of them, grading will depend heavily on your TA. I personally had Jireh and he was amazing at explaining concepts and was an overall very good TA. The midterm and Final were both worth 30% each, and were both mc. The final was not cumulative and was everything after the midterm, both exams were not focused on calculation, rather they were heavily conceptual. Overall, I think I stressed about this class a lot more than I should have, professor Wu does have a very monotone voice, but he is very good at explaining most concepts and would try to interact with the students during lecture. I definitely think that this class was very fair, after taking this class I appreciate the security measures implemented to prevent cheating, as I think my final grade would have been a lot different if they weren't. In all, the best way to describe my experience with this professor was fair, it was not super easy but if you put in the effort it should have not been extremely hard.

Professor Wu's voice is a bit monotone, but his lecture is clear; he posts slides and lecture video, which align very closely with the textbook. Prof. Wu is also very nice, cares about student learning, and occasionally makes quite funny remarks. He replied to emails pretty quickly, was helpful in office hour and gave curve in the end to students who showed progress throughout the quarter.

The labs give a gentle introduction to R and RStudio and should each take about an hour or so each (I assume we truly start utilizing R heavily in Stats 20). You should be fine as long as you follow your TA's guidance and read the lab PDF carefully. The homework assignments are not computationally difficult (the applet does most of the work); rather, you should focus on having a clear understanding of the concepts (when to use what test; the necessary conditions to use it etc). The exams are all multiple choice questions, 2 hours, in Respondus Lockdown Browser (You can bring one piece of "cheat sheet")

Jireh Huang is a very helpful TA; he is good at explaining the concepts clearly and concisely and uses the discussion before assessments to help out with any last minute clarifications. Jireh also responded quickly in Discord when I was confused or had conceptual questions. My biggest impression of Jireh is his dedication to student learning. When he lost his voice, he still typed everything he wanted to explain and clarify in discussion session so we were prepared for that week's lab.

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.

I would not recommend this class because of the grading structure. The overall material is not tough even if you do not come from a statistics background. However, the grading structure has no room for improvement or mistakes.

There are two exams: a midterm and final. Each is approximately 30 questions and theory-based, but the content of the exams is not similar to the textbook questions or lecture clicker questions. The class median for these exams were around a C, and this did not concern the professor. Scoring the median grade is basically a guaranteed B, despite doing extremely well on the final.

I would not take this class again as I felt I was not given the opportunity to learn.

As someone who took AP Stats before this course, it was pretty easy all things considered. There is very little computation in this class and the course is very much regarding the theoretical/practical side of statistics rather than the formulas. We never even used a z-table in this course. All in all, it's definitely not a terrible class if you have prior knowledge.

I'd also like to interject that I took this course as a GE because I'm not a life science major, so I didn't really have as much reason to get too invested in my grade here, but regardless I did give it the best effort I did and scored well on the tests.

The labs and homework are fairly manageable. I managed to finish them in about an hour or two each, but they still did a good job of teaching the basics of R and statistics.

All in all a good course. As for the professor, he is an acceptable enough lecturer given the trying times (this is during the COVID quarantine), but he did a good job of clarifying things in class and gave engaging examples of what he was teaching. Whenever there was downtime during lecture, he would converse with us and just ask us how we're doing and what our student lives are like. He really seems like a nice and personable guy. Also, he was very accommodating when I ran into tech problems during the course trying to take the exams. Great professor.

Also, like anyone who has taken a statistics class on UCLA and left a review on BruinWalk, I am obligated to bash the TA Jake here. He actively disincentivized me from going to discussions because every time I did I felt like I was being belittled. The syllabus encouraged us to work together on homework so long as we weren't just pasting answers without explanation and we would often share solutions after the homework was due via GroupMe. (There was an official Discord server for the class, but sometimes we just wanted to talk as students and help each other through that rather than using the Discord which often felt more formal.) This happened after I left the group chat, but he apparently joined the group chat just to tell us he was "appalled by the number of academic integrity violations." I didn't follow the GroupMe that actively, but unless there was a major breach during the final, I don't recall anything of the sort. Anyway, https://tinyurl.com/y589266c if you're curious about that

I don't know if it was the professor's idea or the TAs but the homework and labs are graded very strictly on accuracy. There are a lot of analysis and explanation questions, if you get the smallest concept wrong, you automatically get points deducted. Homework and lab are 40% of the total grade so that takes a lot of points of the total, making it impossible to get a fair grade. The class is not flexible at all and they are not considerate about the current situation of COVID. I don't know how the class normally is in-person but if you plan on taking this course when online, I highly recommend you take it with a different professor. The content itself is very easy and my friends who are taking stats 13 with another professor are not having the same problem as I had.

Over the global pandemic this professor was not leniant at all. We all had to use a respondus lockdown browser AND a zoom during our midterm. We were told to turn down the zoom but they were sharing corrections to the test questions that many people didnt see. Furthermore the practice tests he gives us were so easy that everyone got 100 but bombed the midterm. The professor and the TAs especially were not flexible considering the stressfull situation of COVID and online classes. There is no option for makeup work and I was overall very dissatisfied with the course and the professor.
