Comment: he is a good professor. i learnt a lot from this course. it's true that his midterm and finals are a bit hard even for a 4.0 kid in berkeley. But still manageable to get into A to A- range if you study hard.

Comment: I'm rating this for fall 2015 (before Ibser switched and taught the class). I just have to give this rating because everyone needs to know what kind of professor he is. As a senior enrolled in the course, when D'abrera was teaching, it was by far the worst class I've ever taken at Cal. My reasons are as follows: made us buy an expensive reader, would start lecture before Berkeley time (addressed this to him via email, and he never replied and continued to lecture early), he would end class 30 min - 45 min early, constantly got side tracked asking students what his ethnicity was (he even said that whoever guessed it right would get a all-paid round trip ticket to any city in America), he instilled competition with the class by saying the top scorer would get an all-paid expense to Australia, he wrote to us a very unprofessional email of him sipping Gin and enjoying pina coladas, he held friday discussions for excel and had a small room trying to accomodate ~200 students (not to mention, he was teaching us excel that was a different version than what the school provided for free, and he ASSUMED we had a stats background. overall, he was absolutely horrible, and I would avoid him at all cost if you don't have a stats background.

Comment: Ibser was a great professor. He was clear with the material and does great at presenting the material (especially being someone who has never taken a stats class). He seemed like anice professor, but he seemed snarky at one of the students who constantly asked questions (felt bad for that student). The quizzes were similar to the homework problems that he assigns. The midterms though were very tricky :(( Also, the GSI's aren't great. If you have Aditya as your GSI, SWITCH! He's absolutely horrible. He would just photocopy book problems, and give them to us during section, and he'd just be on his phone the entire time. And during the last TEN minutes of class he'd ask us which problems to go over, and we'd say more than half -_____-. And he'd get frustrated when students would correct him....

Comment: The Professor's lecturing style is frankly boring and makes you zone out a lot. He attempts to cover too much in each lecture. Try to avoid him. GSI's aren't extremely helpful either and this course is honestly a pain if you haven't taken a statistics course in high school. If you are a social scientist/non-stem major, take Statistics 2 instead. Exams were unnecessarily difficult and irrelevant in terms of what was taught in class. Professor sets 11 homeworks throughout the semester (roughly one per week) along with a quiz every alternate week in discussion (so basically you have to go to it). One midterm and one final exam. No extra credit. Exams are worth a lot so try to do better on them if you take this class!

Comment: It is clear that Ibser is a professor that cares whether his students are learning. He hosts abundant office hours and tries to go through as many examples as possible during lecture. However, the class itself was a relatively unpleasant experience. Devoid of calculus, Ibser's Stat 20 was incredibly boring and frankly of little use to anyone with an actual interest in statistics. Exams were reasonable, though the final was weighed inordinately high (60%). Though this was by no means Ibser's fault, it is worth mentioning that the 9:30 am lecture section boasted the most unhelpful roster of GSIs that I have ever encountered at Berkeley. Lab sections were an utter waste of time. Thankfully, homework only consisted of about 10 problems from the textbook per week. The final grade distribution was somewhat harsh, with 50% of the class receiving C+'s and lower.

Comment: A wonderful professor who is exceptionally clear in lecture. Ibser is patient and always available for students, whether that be in responding to lecture questions, office hours, or staying well after class to talk one-on-one. He also brought a needed levity to the course with his goofy humor. The course itself is quite easy and requires almost no calculus despite the prerequisite. My only issue with Ibser is his 60% weighted final, which I feel would be more appropriate at 40%.

Comment: She's a badass. Super awesome prof. For those of you seriously interested in Statistics, don't take 20. There's so much plug-and-chug and not enough of the theory. I'd recommend taking Stat 134 and Math 55.

Comment: I am very generous on ratings and try and find the positive side on every professor; however, this man is the most unorganized professor I have ever had. He is very nice outside of the course and even during lecture; however he does not teach, he just projects his reader and expects you to commit numerous hours to his class. The book is helpful so read that (EVERY CHAPTER ) and do the problems, it’s kinda hell because there are so many problems but its your only chance to succeed. His curve is generous (rightly so because his exam/final are so F*ING hard) Easy to get a C, hard to get anything in the B-A range. Quizzes are pretty straightforward. Good Luck.

Comment: Perhaps one of the worst professors at Berkeley. Completely disorganized - exams were full of mistakes, didn't even bring enough copies to the final, flow of lecture made next to no sense. Also super unhelpful, since his office hours were before an 8 AM lecture at 6 AM. There's no homework, and section quizzes are super easy. Unfortunately, this only underlines how hard the midterm and final are. After teaching only the basics, his exams go incredibly in-depth, to the point where topics that aren't covered show up. Again, do not take his class unless you are prepared to learn the entire course by yourself and still struggle on the exams.

Comment: how dare you guys not take his class! He thinks he is the best stats professor all over the world. Let him teach stats 20 is a waste of his talent, so he decided to devote most of his time to deal with "cheating" issue. He supposed some of the students have cheated without any valuable evidence and forced them to confess though they didn't. He even chose not to bring enough exams to the final so all of us need to wait almost an hour so that he could have time to print those exams. Lecture is kind of useless.
