Just like all the other reviews have said, he is a relatively easy professor with predictable tests, but you have to work and fully understand all the problems he dishes out. What puts this professor over the top is the fact that he is INTERESTING. If you like gambling, figuring out the prob of a lotto, hes your man. He constantly has practical, real world examples to stimulate your interest. Geez, I couldn't tell you how many times by the end of the class, I said to my friend "class is out already"?

Christou is one of the best lecturers here at UCLA. I can honestly say I still use some of the stuff I learned in his class for my other classes. His tests are extremely tough and they require a lot of your KNOWLEDGE, not your memory. Yes, he allows open notes but if you don't know the material then your notes are of no use to you. You have to study for his tests as if you aren't allowed to use notes. You won't need the text for his class, and personally I think he should write his own text (if he hasn't already). He's absolutely brilliant, funny, all-around great. The greatest thing about his class is the satisfaction of knowing you've actually LEARNED and what you've learned doesn't go away after the final.

Christou is a good professor. He doesn't require you to purchase a textbook for Stats 110A, but you have to be committed to attend lecture everytime because it hurts a lot if you skip even one lecture. He's always around to help and has the most office hours out of any professor I've had. He has a sense of humor which is always a bonus and makes lecture more enjoyable. His final was quite a bit harder and longer than I expected, but not much a negative if you want a good stats professor. Highly recommended!
