First off, Professor Wang is like the opposite of what all your high school teachers would say professors in college are like. She plays statistics songs and will fix issues with the class when students ask or complain. She is one of my favorite professors I have had here at UCLA. She is sweet and kind and her lectures are very precise, in the sense, that it teaches you everything you need to know for the tests and quizzes. I would say that as for statistic labs, which are coding in R, they could be very difficult if you are never exposed to coding before. Luckily, my TA Arjun was a god and would literally do the projects with us in class. He was very good and effective in conveying topics and recapping class. I loved the structure in this class because the work was not overwhelming but kept you on track. The quizzes were pretty easy and the final was extremely easy. This class is an easy A for anyone regardless of your major.

***I took this class online in a virtual format due to COVID-19.

OVERVIEW: Overall, Wang and this class were both pretty good. The difficulty of this class primarily depends on if you've been exposed to the topics beforehand, i.e. AP Stats. If you've taken AP Stats and remember everything, this class has nothing new to offer you and is a free A. Otherwise, prepare to study the topics a bit, but it's still quite an easy subject. The workload is very light for the number of units, and tests are all multiple choice with a period in a 24-hour window.
--
GRADING: Grading is very straightforward in this class, there's no curve and homework is not graded. Participation was required (either through a live Zoom survey, or a short quiz you could take after you watched a recorded lecture). Other than that, there's the weekly quiz, labs, and one midterm and one final. Extra credit was offered for participating in Campuswire, which is really easy. It kind of got out of hand when every question was answered seven times with the same answer, but it's not hurting anyone and it's free points, so why not?
--
HW: There is literally no graded homework. Selected problems are posted with solutions, but are completely optional, so if you've taken AP Stats and feel confident in the material you can skip it, but it is really good practice. Other than that, there's coding labs with R, which sounds intimidating but you can literally just copy exactly what the TA does in discussions and get 100%. Coding is never on the exams, so just follow along during discussions and it's no problem.
--
EXAMS: There were around 7 weekly quizzes that were relatively short. They're not timed or anything, and you can start them anytime during the week, though you only have one attempt. Overall, not a big deal as long as you keep up with the material. Midterms and finals were of the same format, one long CCLE quiz you had 90 minutes to take in a 24 hour interval. Very fair questions, and anytime there were issues, the question got fixed and points reimbursed. Exams and quizzes together make up 60% of the grade, so do make sure you're prepared for them though!

SUMMARY: Wang is a decent lecturer, if a bit boring at times, but she's very nice/approachable. There's many office hours for help, and the Campuswire is super active. I'd recommend this class/professor for a requirement or a GE. Overall, it's quite stress-free, and the accommodations for online learning were great as well.

I took this class as a major prereq and was concerned at first with my lack of experience in stats and any programming, however, prof Wang is an amazing lecturer and this class became one of the easier courses in my schedule and probably the easiest “math” class I’ve ever taken. Definitely recommend wang for stats 10, she’s very organized, clear, and cares about student learning, and accommodates to different time zones by expanding test windows and extending deadlines, etc

Grade breakdown:
20% - Lecture View Quizzes: about two per week and you have a two-day window to take it an indefinite number of times
20% - Online Quizzes: 7 weekly quizzes where your lowest score is dropped
20% - Labs: due every other week (5 in total) pretty tedious but the TAs walk you through everything so just following along to what they do will most likely give you an A in this category; toughest part is downloading R and figuring out errors that may come up in your code, I recommend choosing Andy as your TA!
20% - Midterm: Wang hosts a review session prior along with posting a practice midterm that is fairly similar to the actual one; midterm was pretty easy I think most ppl got a A or B on it
20% - Final: Same reviews and practices as midterm, final covers material post-midterm but content is more difficult imo
1% - Extra credit: end of quarter course evaluation

TLDR: if you have to take this class take it with wang; easy A if you just complete the work, attend lectures and watch section vids

** I took it virtually because of COVID

Pretty easy class, but I took AP Stats in highschool. Overall the Prof was really nice and uploaded slides, recorded lectures, etc; the only warning I would give is that there is some coding in R Studio. My TA uploaded all the code to CCLE so it was okay, but it was definitely what I struggled with most in the class. Prof Wang structured it so that 20% was labs (coding in R, there were 5 labs), 20% participation (by completing lecture view quizzes that you could attempt infinitely), 20% quizzes (there was one each week and she dropped the lowest two), 20% midterm and 20% final which were both around 30 questions and multiple choice. She did assign homework, but it was optional, and she provided the textbook PDF so that we did not have to buy it. She grades on an absolute scale and the top 5% get an A+. I would take this class again for sure.

I highly recommend this Professor Wang to anybody considering Stats 10. First, she is very sweet and clearly cares about the student's well-being. For the class itself, it won't be the easiest class you've ever taken, but it will be far from the hardest. It's around the 15th - 20th percentile of courses in terms of difficulty of those I have taken. You have to put in some work throughout the quarter with labs and such, but it is all extremely manageable. The first 2 sessions with the TA are by far the most important. Pay attention carefully and be prepared to learn the basics of R very fast. After that, the discussions are pretty light. The midterm and final are manageable and there is a favorable grade scale. Grade scale: 20% participation, 20% weekly quizzes (unlimited time, open note, and lowest get dropped), 20% labs, 20% midterm, 20% final, and 1% extra credit for a survey. I suggest taking this class if you have 1 or 2 other hard courses to even out the workload. It's a nice easy - medium effort class where you learn a lot and satisfy a GE requirement, lab requirement, and possibly a pre major requisite.

If you have a background in STATS from high school, great! You're basically set for an A+ in this class. But if not (like me), be prepared to settle for a B. Don't trust all these amazing reviews about her if you are not good at/ don't know STATS.

The grade distribution for this class ensures that if you put in the work, you're on track for lowest a B-, even if you don't understand the material. You get 10% for participation, another 10% for online quizzes that automatically becomes a 100% after you get 25 points total across the entire quarter, etc. The exams are what pull you down. They are extremely complicated, unlike anything she teaches in her classes, and only out of 20-25 points which means your grade drops every time you get 2-3 questions wrong. She also doesn't provide any practice problems throughout the quarter. Its strictly what she goes over in class and the homework problems, but since she doesn't provide an answer key for it, its no help at all. She also takes YEARS to grade assignments which doesn't make any sense to me because its all online and through Canvas.

I probably should have attended office hours to save my grade but she was so judgemental everytime someone asked a question in our zoom meetings that I was too scared to. All around, its a good class with an amazing distribution taught by a terrible and unresponsive teacher, which ruins the entire thing. Sure, its low effort class, but you will come out of it learning nothing, and realizing you were better off taking it at a community college, learning something, and scoring an A.

Being the class that cost me my 4.0 GPA, I had to write something. I thought it would be easy especially given I took AP Stat, but Professor Wang wasn't very helpful especially when I had to make an emergency last minute trip to the Middle East during finals week that forced me to have to take the final in the early hours of the morning to fall within the exam window. You can scroll to the other reviews for more detailed info on the format but there's virtually no margin for error given 75% of the class is from 3 quizzes and 2 exams (of which, 2 of the quizzes and the midterm I scored a high A on) but yet I botched the final (C+) which ngl was really confusingly worded for a lot of questions still shot my grade down to an A-. No curve, no nothing else to save you. Kinda frustrating ngl but it is what it is. Don't take this class C sesh for sure

I took this course summer 2025 as an online asynchronous class and thought it was really manageable. I was taking another class at the same time and was able to get an A in both so the workload really isnt that heavy its just the time to watch the lectures. The class consisted of 3 quizzes, 2 assignments, and a timed midterm and final. The assignments were super easy because the TA just gave you the answers to most of it and the rest was relatively easy as long as you watched the pre-recorded lectures. The class is really not that math heavy, as long as you have the formulas written down its honestly just a matter of inputting the right thing. As long as you able to identify what numbers correspond to every variable youll get the right answer.
The other reviews are true about having little to no practice problem sets but the quizzes are manageable as long as you watch the lectures and prepare a good cheat sheet (cheat sheet allowed for every test). All test were timed but the question count was manageable for the allotted time (quizzes had about 15 and the midterm/final had around 25). The quizzes were also hosted on a lockdown browser with a calculator implemented into it. The questions were really wordy so it can be hard to understand what its even asking for if you dont have a good grasp on the concepts but the practice midterm/final (not very useful) did give somewhat of an idea of what type of questions were going to be asked. The professor also hosted long review sessions before the midterm and the final to help students prepare but she lowk kinda ignored some of the questions in the chat so I would suggest asking your TA since they also held their own reviews before each test.
Also theres a really active chatroom created via campuswire and there were a lot of people helping each other out through there. Also there was 2% extra credit given if you earn 15 participation points. Those points could be earned by attending discussion sections (1 point each), the 2 review lectures hosted by the professor (1.5 points each), or being active in the campuswire (Had its own point system for answering/asking questions). There was no official curve but the TA and professor mentioned that if the average test grade was low enough they would curve. My grade final grade was curved up from an A- to an A and so was my friends so thats dope.

Overall I think this is a fine class to take with this professor as long as you are prepared to actually pay attention to the pre-recorded lectures and use the resources given (discussion sections and campuswire chatroom).

Please read! I want to be honest so you know what to expect.

I took this class as an accelerated 6-week summer course, and despite earning 100% on both assignments and participation and turning in everything on time, I still did not pass. Exams make up 75% of the grade, and the rest is divided between assignments and participation. The grading structure is such that if you don’t perform well on the exams, it’s nearly impossible to pass, no matter how well you do in the other areas.

The class consisted of 3 timed quizzes, 2 assignments, a timed midterm, and a final exam. Math has never been easy for me, but I put in everything I had: daily studying, attending TA office hours regularly, and even quitting my summer job to focus on the class. Despite all that effort, I struggled to keep up. One of the biggest challenges was that after watching the lectures, there were no practice problems to help test your understanding—you were immediately tested at the end of the week. There were times when I thought I understood the material, only to take the quiz and realize I hadn’t grasped it as well as I thought. If you don’t do well on the quiz, it’s just too bad. The quizzes were only 30 minutes, and although we had two attempts, you couldn’t see which answers were wrong, making it very hard to learn from mistakes.

I met with Professor Wang in office hours to express my concern. I asked if she had any review questions we could work on together, but she told me I needed to come up with my own questions for her to help me with. While I understand the reasoning behind this, it was difficult for me to even know where to start, as I wasn’t always sure what I was confused about. When I brought up my struggles and questions, she implied that the material I was confused about had already been covered in the recorded lectures. But what if I just didn’t understand the lecture? It felt like there was no compassion for my situation, and I was left with the sense that I would fail if I didn’t do well on the exams. Additionally, she was slow in answering emails, which made it hard to get the support I needed in a timely manner.

Many of my classmates were struggling with the course too. We would text almost every day, sharing how difficult it was and offering support to one another.

If you experience test anxiety or struggle with timed exams, I strongly recommend avoiding this course with this instructor. Even with a high GPA and a strong academic record, this was one of the hardest classes I’ve taken, and the grade I received was not reflective of the effort I put in. Bottom line: Exams decide everything (75% of the grade). If you’re not a strong test-taker, seriously consider a different professor or session.

By far the worse course I have taken at ucla. If you do not have previous knowledge of Statistics from high school, do yourself a favor a take another professor. DO NOT TAKE THIS CLASS with professor wang. Please keep in mind that the covid reviews are not accurate, certain accommodations were given to student due to the circumstances. I took this class online async, it was a bad experience. You have weekly quizzes that test you on the material, the questions are weirdly worded to throw you off. You are given 2 attempts, however you are not able to see what questions you got wrong after the 1st attempt. 75% of your grade depends on you performance on weekly quizzes, midterm and final exam. She will not curve, so what ever grade you get is your final grade. The exams are multiple choice, but there are questions where you have to input your answer ( a simple mistake in a calculation or a mistake in inputting your numbers could cost you the point on a question). Professor Wang does not give enough practice problems to apply your knowledge and practice before exams. You only have 70 minutes to complete both the final and midterm, one single cheat sheet is allowed but the wording of the questions makes you struggle and waste time trying to understand what is being asked and what you should apply (70 minutes is simply not enough). Trust me when i tell you to look for another professor!!!
