This class wasn't difficult. The content was straightforward and Professor Wu was a good lecturer. There were a few R programming labs, but the TAs gave all the answers in discussion. The midterm and final were multiple choice and while they were on Respondus, they weren't bad. Overall, I would highly recommend this class and Professor Wu.

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.

TLDR; the class is relatively easy, the professor was pretty good and explained well, but the exams were difficult imo.

Admittedly, this class was relatively easy in terms of class content. As someone who didn't take AP Stats, it was easy to follow along, although there were some concepts that I had some trouble with. But all in all, if you pay attention to the lectures and read through the textbook you should be fine. I had this class entirely in person. So his lectures are about an hour and fifteen and he uses powerpoints, which I believe he posts on CCLE. He also recorded his lectures so it wasn't a big issue if you missed some classes; although participation doesn't matter, he did pass around a paper a few times throughout the quarter as a sign-in sheet, but that was for the school, not the class. As a lecturer, he's pretty good; he explains the concepts pretty well and gives a lot of examples in his slides; I found myself understanding the contents of the course pretty well.

The real kicker was the exams. He does provide sample exams for the midterm and final, but I wouldn't put too much trust into those as representative of the actual exams. From what I know, they're recycled questions from throughout all the stats classes. In my opinion, Wu's exams were much much harder than the sample he gives; the samples probably work as a reminder, but the actual exams were more specific and were often worded in a tricky way. It was entirely multiple-choice, about 25-26 questions, each worth about 4 points. But you can see that missing a few questions isn't desirable. I believe for my class, the midterm mean was 71, which he did not curve by the way, and the final mean was about 66. I would say, the quiz questions are the closest to the types of questions you'll get on the exams. You get about 6 or so quizzes on CCLE, one attempt but it's not timed.

As for homework and labs, they were manageable; he wanted everything to be typed. We got 6 homework assignments, the 7th one being extra credit, an extra 2% to our grade. The homework assignments are relatively easy, all from the textbook, and all based on the content we learned, and if you didn't remember, you could look back in the textbook. The textbook is mandatory, but I got it through the Inclusive Access thing. For the odd questions, you can check your answers in the back of the book, for the evens, the odd question before was usually a similar style of question. FYI, some questions had multiple parts. And often, the longest questions for me were the calculating ones; you can imagine how long calculating standard deviation usually takes, especially when you're typing out the equation and showing all your work. The labs are pretty difficult to go through on your own if you don't already have knowledge in R coding; you do have to download R but they show you how to do it. We had 5 labs. I would say it depends on your TA. Personally, my TA (Vincent Liu) was a bit shy and awkward, very quiet, and didn't really explain well, but he basically gave us a walkthrough of the labs; an easy way to ace the labs. He did it step by step (I can't speak for the other TA's), so going to the discussions is what I recommend for labs. I got perfect scores on my labs because of it.

Professor Wu himself is really nice, but I don't think he was all that great at explaining in a way that everyone understands. He basically reads the slides word for word and then gives homework out of the textbook. I took AP STATS in high school but this class threw me for a loop. I would not take this class with Professor Wu if you are NOT a math oriented person, because I feel like the people who did well in this class were people that were in math/science related majors. The midterm and final are HARD, they are much harder than the quizzes and the practice exams, and I honestly did not find a great way to prepare myself for them. Also, do not expect your TA's to be very helpful with the work that you do in lecture. I asked my TA for help on homework questions multiple times and he was unable to find an answer, or was unsure of himself. It's pretty much like you are taking 2 separate classes: lecture, where you learn about introductory statistics, and discussion where you learn basic coding. If you are intimidated by the coding in this class, DON'T BE. Professor Wu does not include it on the exams, and your TA will literally give you all the answers in discussion. Overall, it is not the absolute worst class you could take, but I Personally would not take it with Professor Wu again.

I thought the professor was good. His lectures were pretty boring but if you pay attention the entire time you'll be fine. His slides are super helpful. I found that most people who are STEM majors will find this class to be a breeze, while my non-stem peers didn't do as well.

Assignments and exams are designed to trick you instead of help you learn. Seriously, I spent so much time debugging his stupid PQ numbers instead of learning object-oriented programming.

I took this class as an easy GE, and yes the content was easy but professor Wu did not help and support his students after exams. The class average was a 75 and many people had questions regarding why answers were wrong, the professor and TA both said that they did not know and practice problems would not be provided. The content of the class wasn't difficult it was just more professor Wu's problems were oddly phrased and led to me doing bad in the midterm but made it up in my final significantly (once I realized that the Professor's creates his questions as a trick). I would recommend taking this class with a different professor as the content is easy yet it was just taught not in a good way.

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.

Nice professor. Tries to help a lot. But not very clear. And material is difficult (much bigger step from stats 20!) so be prepared to work. I watched all of Prof Chen's lectures on YouTube and even some extra supplemental lectures from different universities to finally get different concepts in this class. Be prepared to do supplemental work to understand concepts. But he does try to help and genuinely nice guy

I enjoyed this class because the professor is super organized. During each lecture, he essentially just goes over a slide deck that is typically uploaded to Bruin Learn in advance, so I would argue that you could probably succeed in this class without actually attending lectures. The homework assignments, which are worth the bulk of your grade, are a total mixed bag in terms of difficulty level. When I took this course, there were five homework assignments in total, and the first one was ridiculously easy as someone who has previously taken a programming class, and the third and fifth assignments were also very manageable. The second and fourth assignments, on the other hand, took upwards of 20 hours for me personally. Luckily, the professor is very receptive when he is told that some assignments are more difficult, so you will usually receive some sort of class extension for the more challenging homeworks. The quizzes are somewhat difficult most weeks, but they are graded based on completion. Exams are similar in content/structure to quizzes, so be sure to review quizzes in advance of the exams. If you have any previous programming experience, this class is pretty easy.
