Chen is awesome. I absolutely abhor math and had to take this as a prep class, but he made it very interesting and easy. His slides are very clear and logical, and he always stops to make sure everyone understands the material before he moves on. He's also a very good lecturer who can keep me engaged, which is a challenge. Chen genuinely loves stats, and it shows in the lectures. The weekly quizzes are pretty easy, and while the labs are kind of a pain, he gives you plenty of time to finish them. I didn't even buy the textbook for this class, all I need to do is look back at his slides to study for the quizzes. What he teaches is exactly what shows up on the midterms and quizzes. The lectures are even videocasted so if you can't make it to one you can just watch it the next day and its like you never missed it. I had to email him a couple of times and he got back to me very quickly with a helpful response. I highly recommend taking his class, regardless of if you need to or not.

BEST PROFESSOR EVER!! Double majoring in Statistics only because of him, he made me love the subject. He is such a caring and understand professor too. Definitely hope to take future stats classes with him. He explains everything so well, some of the concepts would have been really confusing if it weren't for the way he explained them. He makes stats so simple!

Chen is one of the best professors I've had at UCLA! He's the cutest little guy and his lectures are fun and engaging. He really cares about students and is super helpful and understanding, he wants everyone to love stats as much as he does. I am not a math person but he made me want to take another stats class.
