The class itself is a little difficult, but with this professor it is even MORE difficult. I enrolled in this class because I was too lazy to attend the 8 am lecture, and since I had already taken it at my community college I thought it was not going to be difficult, but I was wrong. It is not the class, it is the professor, the way he teaches, and his exams. There are too many questions on the exams with not enough time, and you can only use a 4-function calculator. So, if you can enroll in the other class, with the other professor DO IT, if not, then just make sure you read the book thoroughly and take really good notes. Fortunately, the book is really good, after the second exam I stopped going to lecture and discussion, all I did was read the book and take notes, and that is how I was able to pass the third exam and the class.

Avoid this professor at ALL COST, unless you either know how to do statistics by hand without a statists calculator. Or you're ready to dedicate the entire quarter to teaching yourself the material. Jafee as a person is very nice, and approachable but unfortunately he can not teach. If you ask him a question 9/10 times you will become more confused than you originally were. The website (TopHat) that he uses has a lot of errors most of the time, and is also confusing. Just don't take this class.

Good Luck

I took this class Fall 2017 and you will definitely need the textbook to do well in this class. I suggest you read each chapter thoroughly and do the practice problems.

I feel like I learned a lot but not from the professor. I had to read the book consistently as well as learn from Youtube and Khan Academy. Jaffe is a funny guy and very cool in office hours but a horrible professor. He wastes so much time talking about his own life and the wording of the problem rather than the equations needed to solve the problem. The class was unorganized and he and his TA's made many mistakes that stressed us out. I highly recommend avoiding this class at all costs, he is not a good professor.

Overall, this class WAS difficult, but, that is not a bad thing.

With Jaffe, you have to come to class having already read the chapter/done all of the practice material. If you do that, his lectures are fantastic and really help to refine your understanding of the concepts. If you don't, you will be sitting there for an hour wondering what the hell is happening and if everyone else silently looking up at him is as lost as you. I attended class both ways, and frankly, after one or two lectures of not being prepared, I never went back to not learning the concepts beforehand.

I think my class felt that Jaffe should have done a better job at teaching us the material, but I don't think many of them took it upon themselves to make sure they were using all of the tools he actually provided for each and every lecture. The quarter is fast and hard, but if you make sure you stay on top of things, the information builds logically and consistently throughout. Prior to this course, I had barely done any math at all over the past 10 years. Now, I feel pretty confident in my ability to understand and analyze research papers and the statistical information they present. All in all, I would say that, if you want to actually learn stats, take it with Jaffe. If all you care about is an A, go with Enders.

Jaffe is a great professor who demonstrates his passion for teaching and his students' success in the class! His lectures are engaging and clear. The first midterm was easy, which made me think I didn't have to study as much for the second midterm. However, the second midterm rocked my world. It was SO hard and I was extremely crunched for time! We do get a cheat sheet now for the midterms which is nice!

Jaffe was clear, really funny, and always had a great attitude. He was very approachable and really encouraged students to come to his office hours. He allowed us to have a cheat sheet for the exam and did his best to accomodate our concerns. I went to almost every class, some of the discussion sections, and review sessions. The TAs were approachable and made the review sessions based off what would be on the exam. I mainly studied off the discussion and review session slides (as well as top hat).
Overall, I liked the class a lot and would recommend Jaffe again.

这个课不太行，professor把很简单的东西讲的乱乱的，unorganized，confusing，not focused。上课还挺幽默的，但是花更多时间讲笑话，该讲重点的时候讲不清楚。基本不能skip lecture因为他要边上课边让我们用软件回答问题。综上，建议等待换一个professor上psych100a。

I don't think Dr. Jaffe's overall rating for this class does him justice. If you're not a fan of integrated learning platforms (this class relies heavily on TopHat--look it up) or exams making up most of your grade, this may not be the class for you. But Dr. Jaffe is a great lecturer and he's very approachable if you have questions about the material.
