If you took AP Stats, you're set for this class. If you didn't take AP Stats and stats is a completely new concept to you, you'll still be fine because Professor Cha does a really good job of explaining things. If you have any questions, she's very patient and puts a lot of effort into ensuring that you thoroughly understand whatever you're learning. She also posts lecture slides online, so you can always refer back to those too. You'll still have to attend lecture because of iClicker questions, but I usually just left class after the first iClicker question; you only need to answer once to get credit for the day. Stay for the entire lecture if you're learning something new though! I think it would be more useful to hear her teach instead of just reading off of the slides.
Each week you get a quiz, and every two weeks you are assigned a lab. Both are easy. For the quiz, you can look at the slides if you need to. For the lab, you work on it in your discussion section with your TA; while discussions aren't mandatory, you should definitely attend if you're working on a lab that day. The labs are done through this confusing program called Fathom, and you'll need to see the TA do it to understand how to navigate the system. And besides, the TA will basically be giving you all the answers you need for the lab, so why not attend?
The most important piece of advice I have for people taking this class is to KNOW WHAT YOUR CALCULATOR CAN DO. Since I took AP Stats in highschool, I knew all the shortcuts and functions my graphing calculator (TI-84) could perform and I didn't really need to use the formula sheet that Professor Cha gave. I'm not exaggerating when I say that the graphing calculator can literally cut your work time in half.

Grade breakdown:
Exams: 60% total, 30% each
Online Quizzes: 20% total out of 8 quizzes (and then drop your lowest 2 scores)
Participation: 4%, received by answering at least one clicker question during lecture
Lab: 16% total (4% each lab assignment) drop lowest score out of 5

The lab is absolutely nothing to worry about. In lab all you do is code in R (coding program). It's not hard at all though because the TA does all the work and all you have to do is copy it into your own laptop. I did work for other classes while my TA explained stuff and just looked up when she would scroll down so I could copy down more code. That being said, the lab didn't really have much to do with lecture. It used the same statistical concepts but you won't need to code for exams or anything on the concepts from class aren't really elaborated on, just shown with code. Pretty much a free 16%.

Quizzes aren't too bad either and you get to drop your lowest two scores. You have the weekend to do it on your own time online and so you can use your notes and everything. Good place to study from for the midterm and final.

I didn't really pay attention during lecture but still came out with a B so the class isn't all the bad, especially if you've taken AP Stats or something (unlike myself). Would recommend. Professor Cha is really nice.

If you have taken AP Stats and you are looking for an easy A, take Stat 10 with Professor Cha. Besides I have to go to every single lecture due to clickers, this class makes my life so much easier. Her slides are very helpful.

Maria Cha is the nicest professor I have ever had. The material is pretty easy and everything is on the slides. I feel like how well you do on the midterms is dependent on how well you've prepped your cheat sheets. There's no final which is really nice, so you can focus on other finals during finals week. The material on the second midterm is definitely harder than the first just because there's a lot more formulas and scenarios to keep track of, but as long as you pay attention to the lectures and write it all down on your cheat sheet for the midterm you will be completely fine. This was a really calm, relaxing GE to take during winter quarter.

Great class, was kind of a shock as to how easy it was because all of my other classes have required so much studying and work on a daily basis and this one just required some revision before exams and a R studio lab every other week. Definitely lightest, easiest course I have taken so far. The exams were pretty decent plus you got a cheat sheet for them, still recommend going through all the slides and practice problems on slides though. I did not use the textbook once but did study a lot through khan academy stats just for practice. She gave participation points with clickers and was a great lecturer. The labs would have been hard to complete on your own I think but luckily I had a great TA (Sun, Y.) who literally did it step by step for us haha, so it was very simple.

Loved Professor Cha. She's really kind and truly cares about student learning. In addition, she had a really calm presence in class that kind of made this class almost feel like therapy after a busy day. Attendance is required (iclickers) but honestly it's better to go anyway because its much easier to learn all the material in class with an actual lecturer as opposed to spending maybe 2 hours self teaching the concepts the night before the exam. Anyway, the class is really easy. There are weekly labs but the TAs pretty much provide the code so all you have to do is attend discussion. The weekly quizzes are really easy as well and are good practice for the midterms. Her exams are nice, they're all multiple choice and don't necessarily have any curveballs. Overall, Stats 10 is a super easy class. If you've taken AP Stats then thats great; if you haven't it's still super super easy. You might have to pay a little more attention during the latter half of the class but the material is still really intuitive. Anyway, if you want to optimize this class as an easy GE, I recommend paying attention in lecture and going to discussion so you won't have to spend any time at all studying outside of class.

pretty easy class. you literally just have to show up and do all the work she assigns. no extra studying because you get a cheat sheet for every exam. got a B+ because i’m dumb

Cha is a good lecturer. The material in my opinion is confusing but if you're good with formulas this class will be fine. If you're not you might struggle because her tests are pretty hard. She is helpful in office hours and she gives you a practice exam and cheat sheet during the exam.

This was the first class I took at UCLA and it was a great one to start with! Even though we only had one live session, I can tell that Prof Cha is nice.
The grading is fairy lenient:
20% lab (3 labs, basically follow along with the TA as they teach you how to code with R)
20% check-ups (8 check-ups, and they're CCLE questionnaires taken for a participation grade)
20% quizzes (4 quizzes, lowest score is dropped)
20% Exam 1
20% Exam 2
There are some textbooks recommended for the class, but I purchased neither of them and I was fine. But, if you feel you need extra practice, you should probably purchase.
Exams slightly mirror the practice exams (which Prof Cha provides). The concepts are the same on each, but the questions aren't necessarily the same type. You can succeed on the exams by taking the practice exams then going back and correcting your mistakes just to make sure you have a solid understanding of everything.
The class overall wasn't too difficult, but that's probably because a lot of the concepts had already been introduced to me in AP Bio and AP Psych. I probably put in around 5 hours of work for each "class" day (more like recorded lecture day lol. It breaks down into 2 hrs of lecture + 1 hr of TA + 2 hrs of condensing the slides into my own notes). I think this time commitment is reasonable for a time-crunched summer session.
Overall, just put in the work and you will get the results!

Overall, this class is a wonderful class to take as a GE if you are into statistics or math in general. The material covered in this class is very closely related to any stats material covered in high school, an overall great introduction to stats. The professors presentations were very helpful as they covered all of the necessary material. Also, the tests were fairly straightforward, relating homework material with class material. I would definitely recommend this class to another student as it was an easy class for me over the summer.
