Not hard to pull an A because:
1) midterm+final not too hard
2) a good portion of your grade is assignments that you can check with TAs for accuracy if necessary
3) extra credit: up to 0.5% for Campuswire discussion, 0.5% for section/lab attendance (can miss up to 3 sessions), entirety of last lab
4) lowest grades in each portion of grade (quizzes, hw, lab) is dropped
5) no clickers/participation for lecture
6) unrelated to grading, but textbook isn't required though hw assignments refer to it. you can get by with pictures from friends or the pdf
7) some real homies on the Campuswire discussion forum (like Piazza but less ugly) pretty much give answers out to questions if you get stuck on assignments bless yall

Despite all this, I found it harder than a lot of the other LS major prereqs. Before you think poorly of me, this material is SO DRY my constantly chapped lips are like an oasis in comparison. First day of class, "new quarter new me" mentality in place, and I still fell asleep. It's really not Mike's fault that I found the course material boring-- he's a pretty funny guy and not uptight like some profs can be at times. Class attendance at lectures the few times I went was ABYSMAL because you can just watch it on 2x on Bruincast if you want (and still probably nod off while watching the video too).

The class is overwhelmingly hard, and I don't recommend anyone taking it. Lectures are clear, but the tests are non-sense. We are tested not on the ability to analyze data by R, but simply some weird rules and edge cases. Homework are good, but gradings are incredibly strict. We can be deducted for more than 10% of homework grade just because of style of coding. As a "fair" CS student who almost got an A in every CS class I took, I still find this class very confusing.

I am not a huge fan of statistics, but Tsiang made this class bearable. He’s such a nice person and you can really tell how much he cares about each student. He was very generous with grading, and tests were pretty straightforward, though some questions are trickily worded. (However, he allows cheat sheets) The coding labs were difficult, and somewhat harshly graded, but the last lab was entirely extra credit, so it was all okay. I wish every professor could be like Tsiang. He loves the class material and his students, and it really shows. Take this class!!

Tsiang is an amazing professor! Take this class with him. The midterm and final are somewhat aggressive but he lets you use a sheet of paper for notes. Make friends and do the homework and labs together and they are not too bad. Here's the grade breakdown:
Homework- 16% (Lowest is dropped)
Online Quizzes- 16% (Lowest is dropped)
Labs- 18%
Midterm- 20% (Was 30 multiple choice)
Final- 30% (Was 40 multiple choice and he gave 2 extra credit questions)

This class was great. Labs were a bit annoying but not terrible and TA’s were super helpful. The homework was also fine (he drops the lowest one). We had weekly online quizzes (he drops the lowest one). You didn’t even have to go to class to understand it because the class is bruincasted and slides are online.

Wow...... what a quarter. First off, if you do not have any programming experience, the homework is gonna take a lot of your time as it did for me, also the grading rubric for the homework is very specific so you can lose points very easily. Homework was very tedious especially when it had that killer question on each that many students struggled with and had to go to office hours for.

Second, the tests were difficult because of the time constraint and the free response questions. The multiple choice was easy for the most part, but some of it required answers that only you can get from messing with R.

One thing I regret in this class is taking it with a major class that made balancing classes very difficult. With that in mind, if you love R or need this class for your major,minor,etc, and have easy classes to balance this out with . Go for it. As for me, I gonna take a long break because this class sucked out a lot of energy from me. Peace and Love folks.

Mike is awesome, I didn't even do very well in the class but he was always super helpful.

Best professor at UCLA!! Exams are extremely straightforward, just make sure to pay attention to little tricks in the conceptual questions. Learned a lot while keeping the workload light. 10/10 recommend!

MIKE IS THE GREATEST PROFESSOR AT UCLA! He is so so sweet and funny for a stats teacher! Seriously, if you have to take stats, do not take it without Mike. He uses Parks and Rec references in like every problem. He also believes that your mental health should not be sacrificed for grades. He leads you in breathing exercises before every test. The tests aren't that hard because he gives you a cheat sheet and thorough practice problems!

Contrary to prior quarters, this class has been changed and made far more difficult than it used to be. There were two midterms and a final all of which were multiple choice and written. The exams were difficult and tested minute details of R, but the curve made up for them. Nonetheless, studying for the exams was difficult seeing as though we’d receive homework assignments due the same day as exams only to be postponed at the last minute after students have spent all week doing them instead of studying do to their length. The homework assignments were lengthy, time consuming, and difficult, but if you put the time into it you will genuinely get a lot out of them. You will actually gain a lot of knowledge in R from this class and you will be more prepared for 102A than students from previous quarters were if you are able to invest the time into the class. The TA Jake is not as bad as others depict him to be. He extended his office hours almost every week an assignment was due. His office hours were the most helpful of all the TAs, so definitely take advantage of it. As for the professor, he genuinely cares and only real downside about this class is the time you need to spend on homework assignments and the group projects. I definitely don’t recommend taking this class unless you’re a stats major/minor or considering becoming one. Also, if you do take this class try to take a lighter course load as this class will take up a lot of your time especially if you do not have prior programming knowledge.
