He's awesome, and stat 13 is a good class. You might be kind of put off the first day cause he has an accent and sometimes it seems like he's yelling at you when he talks (he's not) and he goes super fast through stuff, but you'll get used to it, and by the end you'll probably really like him. There might be a textbook listed under the schedule of classes page, but don't buy it, cause you're not going to need it. He gives out handouts with notes, examples, the formulas - everything you need to know - during class. So you actually have to show up to lecture, otherwise there's no way to learn it. The material is pretty easy, though - if you just go to class and pay attention, and do and understand all the homework, you'll be fine on the tests. The lectures are 90 minutes, but it goes fast - one time we even took a break in the middle to watch his soccer team play. He's a very chill guy. He even canceled our lab on the tuesday of inaugaration so we would be able to watch it live. The labs are really easy, and the discussion sections aren't mandatory. If you wanted to, you could skip the lab sections too, because he usually gives you the assignment page in class, and you don't need any special software to do them. (its all done through applets on his website.)
He's a good teacher, too, in my opinion. All he really does is read you the notes and work through example problems with you, but somehow when you listen to him, it makes a lot more sense. I've had other math teachers that did the same thing, but with them it didn't really help.

Tips for the exams: buy a binder. Its all open note, but you want to be organized and be able to find stuff. For the 1st midterm, make sure you're comfortable with the using summation to find all the ways a certain outcome could occur. Its not in the handouts, but he goes over it a bunch of times in class, so write down all the examples. For the final (which is not really cumulative, even though in the beginning he says it will be), make sure you understand how to draw the two distributions (of the null and alternative hypotheses), and how they overlap, and where alpha and beta are. Also, know how to find the power of tests. This was stuff that wasn't emphasized in the homework, but came up on the exams.
Its not a hard class at all, as long as you spend maybe 2 hours a week on it, and the material is slightly interesting. Its a good way to get lab credit for a GE, and probably a lot easier than other science classes.

Christou is a great professor. One of the first things I noticed about the class was that he didn't make us buy a book. Everything we needed to know was in the packets he handed out at the beginning of each class. He is a very genuine person and can be pretty funny as well. He gives more than enough examples with his packets to make sure students have enough practice with the material before the midterms, and usually gives the answers so we can check our work. Make sure you don't miss lectures. Since there's no book there it would be difficult to catch up on the material you miss. Understanding the homework will generally prepare you for his exams. He is the kind of professor who knows your name if you speak to him just a few times. Though this seems irrelevant, one of the things I liked most about him was that he understood there was a world outside the university. We once took a break during class to watch part of a soccer game and he even spoke to us about the presidential election. My only complaint is that he speaks rather quickly and can be hard to keep up with, but there is a lot of material to cover. I think what I learned is very applicable in real life situations and I would recommend him to anyone who takes stats.

He was an excellent professor, so take his class if you can. The course covered half of the stuff learned in Stats AP for those who took it. He helps you to really understand the matter. The tests were fair and there is no final. You have three midterms instead but you get to use your notes on them. The labs and discussion were easy ways to get points in the class. Go to the lectures so you can understand the matter because unlike some other classes he over plenty of examples instead of just giving you the concepts.

Christou is awesome! His lectures are extremely well-organized, he's got a good sense of humor, and his tests are very fair. He makes it clear that his primary concern is that his students learn the material... all of our tests were open-notes. Take him if you can!!

I dont know why everyone is saying that this professor cares about his students. Going to office hours is useless because he doesnt even answer your questions. The class isnt as easy as he says it is. You have to study and stay on top of this to do well.

Prof. Christou was great. I hadn't taken any stats in high school or 3c like a lot of the class, but I still managed to pull through and get a B+ with pretty little effort. His handouts were helpful and his lectures were well organized. He also knew everyone's face in the class (and quite a few people's names). I highly recommend the honors section if your looking for a way to get some honors credit with barely any extra work. A couple homework assignments and one hour a week sessions that usually didn't even last the whole hour. Overall, I really liked Christou and high recommend him :)

i tried taking stats 13 w/ this prof during winter, but dropped it at the end of 3rd week after the 1st exam b/c i had other 3 classes to focus on...i took in what the other said about this class...the hw was definitely easy and doable, especially w/ TA's help...but hw and labs are definitely time consuming...i really recommend going to OH's if stuck on probs, and not just getting the answers w/out knowing how to do it...i find the 1st exam to be okay...it's only easy if u know the material really well...open book exams, but it won't help if u don't know the material since u only have 50 mins to complete it...it's basically made so u are competing against time to finish the exam...i also found the last problem on the 1st exam to be tricky...if u are not a stats person...especially at probability stuff...u definitely have to work on it b/c it won't be that easy.

Professor Christou is a really good lecturer. Though he gives off a rather mean first impression, he geniunely cares for his students and will do whatever it takes to help a student understand the material. His lectures are straightforward and to the point--he rarely goes off topic w/ side stories or what not. He is a fair grader and makes reasonably hard tests. For Stats 13, the midterms were extremely easy, but his final was a bit difficult. Still, this class is not difficult at all (which he will tell u himself the first day of class).
