Some questions were weirdly worded on tests. If you've taken AP Stats (which I did before) then you should be fine if you brush up a little bit before exams. Also, knowing how to input everything into the calculator is pretty helpful because most of the time if you enter things wrong into the calculator you won't get an answer on the test because it's multiple choice and assumes you will make your mistakes doing it by hand. Other than that, I didn't pay too much attention in lectures but still did fine.

This class is fairly easy, up until after the first midterm, after which the class gets way harder if you have fallen into bad habits (like me). Cha is an extraordinarily nice person however and really takes great care to always stop and see if there are any questions, and she will explain the material until she feels that everyone knows what is going on. There are biweekly labs due and weekly online quizzes, as well as clicker questions in class to check for participation. She also posts recommended practice problems from the textbook, but they are never checked. A formula sheet is allowed for her exams.

If you have taken AP Stats no worries as this class is easier in my opinion. Tests are very fair and you can write all the things you need on a sheet of paper.

Cha is a great professor!! I HIGHLY RECOMMEND her class! Her lectures are easy to follow and she constantly repeats the harder materials in case some people didn't get it the first time. Her exams are really easy as they are very similar to her quizzes and the examples that she goes over in class.
The discussion sections are essentially our lab sections. So as long as you follow the TA's instructions, you'll be able to get the lab reports done as the TA tells you what to do.
This class is by far the best and easiest class I have ever taken at UCLA. 10/10 recommend!

Cha was very clear in her slides. She does the problems on the projector/board with the class to walk everyone through. She answers questions in class and also has office hours if you're really confused. She didn't give mandatory homework. She gave weekly quizzes that reflected what we saw on the midterm/final. In addition, she drops your lowest lab and quiz grade, which is extremely helpful.

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.
