If you'd taken stats 10 before this class, this class will be a breeze. That being said, tests can be hard if you do not pay attention in class. All concepts on the tests are gone over in lectures and you should attend his OH or Stacy's discussion if you're confused. Tests are purely conceptual so no calculation is required. Homework is online and 100% doable. No textbook required so more $$ saved. I highly recommend Stigler for psych 100A; he is kind and cares a lot about his students. One thing though, is I am not a big fan of his lecture slides because personally they are not useful for studying (again, pay attention in class and attend lectures). His lectures are recorded though but you don't want to wait until the day before the exam to watch them. Oh! And he allows one cheat sheet during midterms/final! :D

Unrelated:
During the final, a girl came late and he comforted her and told her she can still take the final. I just thought it was such a sweet and beautiful moment when a professor understands his students. Although I wish I had gotten an A+ in his class, I'm pretty satisfied with an A.

Take PSYCH 100A with Stigler. As a first-year, I've heard that this class, along with 100B, was one of the weeder classes for Psychology department majors, so I was pretty scared. I came in with no statistics background and he was able to teach the subject well enough for me to do well on his tests and the class as a whole. The class is longer than most classes, timing at an hour and fifteen minutes, but Stigler makes class quite entertaining and throws a few jokes in. It's obvious he is passionate about the subject. He is extremely generous in his grading; even though his class is graded on a straight-scale, he does not give out any minuses. He had an opportunity for 1% extra credit on our final grade if 90% of the class did course evaluations (which sadly, was not fulfilled) and had 5 extra credit questions on our final. He is also very caring and approachable in his office hours and is willing to help any student. That being said, if you don't understand something, go to his office hours; they are life-saving. His class is purely conceptual, you will do absolutely no calculations on any exams and will not even need a calculator for this class. All resources and materials needed in his class are FREE, including the textbook! Exams are done online through Qualtrics and you are allowed one 8.5"x11" sized "cheat sheet" per exam in which you can use both sides and can be typed. Homework was done through the online textbook and was due weekly. Participation does matter in this class, but you are able to miss two lectures and still get full credit. He also records all of his lectures and uploads them onto YouTube. In the end, this was one of the few classes I actually looked forward to attending; that says a lot about Stigler.

Stigler's class was very doable. I hardly studied for this class, and did all the homework (which is required). Be sure to write down important concepts that he explains during lecture. I basically did that and wrote some stuff down on my review sheet, and got an A. His exams are now done online during lecture. Also, he does NOT down curve. I highly recommend taking this class with Stigler.

I guess the reviews below won't match with mine but I personally did not enjoy the class at all and felt myself constantly frustrated by the way the course was taught and how I was learning from Stigler. As the other reviews mentioned, the course is 100% fully conceptual meaning there will NOT be any calculations on the exams at all, which I guess is a good thing if you are looking for a statistics class that does not involve a lot of heavy math work (or any in this case). The concepts, are tough to understand, however. For the final exam, I spent days on end rewatching all of the lectures and writing down every single detail to understand why different statistical concepts were the way they were, which is the way this class is set up. Stigler is a VERY nice man, I will give him that. He completely understands and sympathizes with his students and will constantly ask for input and then implement what the students give him. However, the course structure is a little disorganized for my liking and I just felt that the class was really challenging (for me at least).

100A with Stigler was wonderful! He doesn't make you calculate anything. It's ALL conceptual.
The material is pretty straightforward and it's basically Stats 10 with a few more concepts. There were weekly homework assignments that were quite long, but I found them very helpful since they introduced the concepts he was going to lecture on. Stigler's lectures were always interesting since he's so passionate about stats and cares a lot about students understanding the concepts. His tests were pretty easy if you understood his lectures. If you're having trouble in the class, go to his office hours or to the TA run sections. (If you have Stacy Shaw as your TA, I'd highly recommend attending her labs. She explained the concepts very clearly.) I cannot recommend Stigler highly enough. Take a class with him if you can.

If you are a math person, this will be the easiest statistics class you could ever dream to take. Stigler really focuses on making sure students understand the ideas behind the numbers, and his tests do not include a single calculation. I got an A+ on this clsss without doing any revision for any midterm or final, but listening and understanding all concepts explained in lecture. He's also really passionate about statistics and student learning generally, and a great professor can always liven up a Boring subject. Take Psych 100A with stigler.

This class has a cool professor. However, it is important to pay VERY close attention to the syllabus. Some of his policies are inconsistent with UCLA'S policies, for example, his grading system. He calculates B's as ranging anywhere from 80% to 80.49%, so although this may not seem significant, consider the fact that UCLA calculates B's at 83% and above. Since he includes a whole new scale, your perspective on how exactly getting a B in his class will affect your overall GPA is skewed, as you know that a B at UCLA correlates to 3.0 points; additively, a C+ correlates to 2.3 points and a C correlates to 2.0 points. Since his scale does not align with that of the schools, it is unnecessarily difficult to really know how well you're doing in the class until the end. I don't know why UCLA does this haha, but pretty much everyone feels tricked at the end because the professor and the institution are not being consistent.

Like the review previous, Stigler is one of my favorite professors at UCLA. I came in with no stats experience at all, and I was afraid going in. He is very passionate about what he teaches, and you can really tell. About the course, there are NO CALCULATIONS WHATSOEVER. He wants to understand the concepts and why you get certain values, etc. Not going to sugarcoat anything, but the concepts are really tough to wrap your mind around. However, he cares a lot about his students, he wants them to do well, and he is very understanding. He told us he really was going to miss this class, and I wish he taught 100B (he didn't want to teach that class because he thought it was a ridiculously hard class). He doesn't curve down. This was his first time teaching at the undergraduate level since a decade ago. He will choose the higher grading distribution for your grade.

If you have the option of choosing between Jaffe and Stigler for 100A... TAKE STIGLER. I took Jaffe in Fall 2016 and he was the WORST professor I've ever had the misfortune of taking... I won't even say anything more about him. Stigler is INCREDIBLE. Literally the BEST professor I've ever had. I hate statistics and he actually made the lectures interesting because he was so passionate about it. He cares so much about his students, he wants them to do well, and he is very understanding. (He also does NOT curve down, so don't pay attention to his previous reviews. He just doesn't curve, but has 2 methods of grading and gives you the higher grade of the 2 methods). This was my favorite class this quarter and I highly, highly recommend Stigler. He is a blessing to the UCLA campus!

cool guy, very nice, easiest psych100 on campus
