Lew was a very good professor with pretty aloof TAs. She was an amazing lecturer and extremely personable. She learned everyone's name in the class and made a strong effort to make sure everyone knew the material that cared to know it. The work in the class was quite easy and homework and labs are easy but you can get docked on points quite easily if you're careless and leave small mistakes. You may not think you need to go to discussions but you get free answers which is pretty awesome. The labs aren't too hard either, just have a lot of diagrams included. As for her exams, I never liked them. There were usually multiple errors and she was trying to change them during the exam which is just frusturating, and they questions are ten times harder than any homework problem. But, if you can figure them out, you'll do well in the class, because her curves are very good usually. Not hard at all to get a B in the class but an A is difficult. I recommend her strongly.
Summer 2018 - Professor Lew is one of the best professors for STATS 13. Her office hour is super helpful in clarifying the materials. She did not push her students to learn all the materials. Instead, she really wants her students to understand the materials well before moving on to the next chapters. This class does requires some times in reading the textbook and coming to her office hours, but it is all worth it when you finally received your grade.
Summer 2020 - Professor Lew is absolutely fantastic. Having come in with little to no programming experience (AP CS in high school), she makes learning R fun. Especially during COVID, she has been so understanding of students' struggles (e.g. recording lectures, providing opportunities for up to 10% extra credit, dropping lowest grades). Though she might seem intimidating, I would recommend anyone to attend her office hours at least once: she has so much professional experience in the stats field (i.e. not just as a professor) as well as so much wisdom to offer. This class is primarily based on projects and assignments, and unlike the other professor who teaches Stats 20, there are no formal exams. I'd say that it is very easy to earn a decent grade if you put your best foot forward; even if she were not as lenient because of the pandemic, I'd assume it'd be the same. Although I haven't received my final grade yet, I'm very confident about my performance in her class because she makes it clear how to earn points/what she's looking for (tip: don't over analyze instructions!). Some other notes: (1) there is no curve for the course, though I don't see when one would be needed and (2) don't get the recommended textbook. Because of her, I feel like I have a solid understanding of R and have decided to pursue a minor in stats! I'd love to take any future courses with her.
Spring 2017 - Professor Lew didn't teach this class. An undergrad did, Connor Hennen. I think she was his advisor or something. But it was a cool class. Nice guy, tried hard to introduce us to the data science world in an exciting way. Don't know if it'll be offered regularly, but I'd recommend it.
One of the most awesome professor ever in UCLA. She is so helpful during her office hour. She would try her best to solve every problem you have but without telling you the answer directly. The lectures were OK,just like other normal lectures(the good ones). Not to mention she brought a whole bag of candy for the class on Halloween. I will definitely take her again if I have a chance if I probably will for stats 140SL. BESTEST professor eva!
