He is a very cool and helpful teacher but is sometimes bad at explaining things. He's super approachable and funny though, which makes up somewhat for this class being very difficult. I recommend using the book as a backup supplement

I have never taken a statistics class before this one but using the book, it's pretty straightforward and easy to figure out yourself. Going to class is good because sometimes he slips questions from things he's talked about in class on the multiple choice midterms, but it isn't too helpful. The TA's for this class were really good, they helped outline things very straightforwardly but I feel like Jaffe always went on tangents. I've heard he's better than other professors, so he's probably the best option, but this class isn't going to change your life.

He is a very charming person but not a great teacher. He didn't really teach us anything the whole class he just keeps asking questions to the student which really doesn't work in such a large lecuture. I think it's impossible to sustain my attension during his lectures but hey you gotta do what you gotta do if you wanna take psych!

The class is pretty easy as long as you're comfortable with all the formulas presented in class. Professor Jaffe does an okay job of going over them in class, but the textbook is especially useful. Lecture slides are available online, and his lectures are the same as textbook chapters so if you're willing to read the textbook, going to lecture is kinda optional. Section is also optional; it's just review of the week's material, but those slides aren't posted.

Jaffe also doesn't write his own tests and a fair amount come from an optional online website called "Personal Trainer" that's available with a new textbook but is also available separately. The website has a lot of good review and practice questions so I would strongly recommend it.

Jaffe is a great professor and nice human but the course structure was unnecessarily challenging for the statistics you actually need to know for Psych for 100b. I do not feel I'm better off for knowing all the formulas I know now because the important thing to know is when to use which tests in 100b and beyond- the computer does the rest and I'm frustrated I spent sooo much time energy and stress to do well in his class. There are easier professors and their students don't flounder later.

Prof Jaffe is such as cool down to earth guy, and he knows how to make the lectures engaging and funny. I would not say that he is a bad teacher at all, like a lot of other people here said. This is a just hard class to teach, and no one takes this class voluntarily, they just take it to get into the major. I think that that is why no one likes this class. Overall, Jaffe made the lectures fun to go to. It was very manageable. There is no homework, just one or two online quizzes due each friday. There's two midterms and a final. 50 multiple choice questions. They are not cumulative. The thing that helped the most was reading the book that corresponds with the lectures. He covers everything pretty quickly in lecture because there is a lot of material, so you will not do very well unless you read the book to further understand the lectures. There's also an online supplement that you can purchase that will give you extra practice problems and mini lectures, but it is not necessary as long as you use the book's practice problems.

I am selling the book if any one is interested. It cost $130 but I'll sell for $60. Contact me at mendozachrissy@yahoo.com if interested

Jaffe was always in a good mood. He has a really cool story and I feel like he is the kind of person who probably has a lot of wisdom to share. As far as the class goes, the textbook SUCKED but he knew it did. It was online, had tons of typos, and explained things terribly. Luckily he was a good enough teacher that I could understand it without the book. Highly recommend him as a professor, but hopefully they've changed textbooks by now!

Dr. Jaffe is a great guy! His story is very inspiring and you can tell he really loves his work. The midterms were fair and there was plenty of review. Somtimes I felt like I was just memorizing past answers instead of actually learning material though. I wish he would not follow the given slides and do more of his own. He is very open to help you out and is a great presenter though. I ended up with an A-

Psych 100A with Prof. Jaffe was great! He made the material interesting and was always willing to help if you came to him. To succeed in this class, keep up with the material and utilize your peers! The powerpoints and book are awesome study tools. I HIGHLY recommend taking 100A with Jaffe.
