This course has its pros and cons.

I won't go too much into the grading system because he should have this written in his syllabus, but the grade is based on participation (answering questions in-class through TopHat), homework (completing modules on TopHat), weekly quizzes (higher score out of two attempts is recorded), two midterms, and a final. All of his tests are 50 multiple choice questions, with a good mix of conceptual and calculation problems. The two midterms are in-class (an hour and 15 minutes long) and the final was two hours. Get your easy points by participating in class, doing the modules (based on completion), and the quizzes.

Most of you are probably concerned when reading all of these previous reviews. Yes, most of them are accurate, in that Jaffe is a cool person but not a great professor. He does his best to explain concepts, but the way he delivers these ideas isn't really clear, and many times you are prone to zoning out during class. He has office hours, which many people took to their advantage. I personally didn't do this, but if this is how you learn, go and ask him questions and he will solve some example problems with you. Also, DO NOT RELY ON THE TAs. I don't know if this happens every quarter, but the TAs I had this past quarter were no help. The "discussion" section they have really isn't a discussion at all. They just present powerpoints of concepts Jaffe went over in class and literally repeat the same things he said. For me, this was a waste of time, and by week 3 I chose to study on my own.

Studying on your own IS AN OPTION. Sit down, read through the modules carefully, google/watch YouTube videos on concepts you don't understand, and actually work through the quiz problems. Study with a friend. Jaffe emphasizes the importance of the textbook for this class, but it is SUPER EXPENSIVE and I did just fine without buying the textbook. If you want extra practice, you can borrow the textbook at Powell and work through the problems relevant to that chapter or the midterm/final you are studying for. Definitely make time to practice problems (especially for the second midterm and the final) and work to manage your time for the test because many students complain that they don't have enough time to work through the test.

That being said, this class is like any other stats class and don't be worried if you have never taken stats before. This was my first stats class and I was still able to pull through by studying on my own and using whatever resources were available to me. Find what works for you, whether that be the module or the textbook or Jaffe's lectures/office hours.

This class was pretty manageable, especially if you are willing to teach yourself. I had heard from previous students that Professor Jaffe's lectures and TopHat were not very helpful. After attending a few lectures I found that I agreed so I stopped going to class. Discussion is essentially the TAs lecturing on that week's material, but the slides are posted, so I also did not attend discussion. The TAs host review sessions before the tests which are helpful because they outline all the material that will appear on the exams. However my TAs were not particularly good at explaining concepts and frequently made errors. I noticed some mistakes on the review slides the night before the final! They also had a very dismissive and unapproachable air that did not encourage questions. I studied by reading and taking notes on the textbook and using all the resources on Personal Trainer. The TopHat modules are confusing and not very similar to tests so I wouldn't use them to study. Professor Jaffe allows you a cheat sheet (front and back) which I feel is very generous and his tests are pretty reasonable. The biggest challenge for me was the time constraint and the stupid four function calculator he makes you use. Overall I didn't enjoy this class and I didn't think the in class resources were helpful, but it wasn't difficult to teach myself the necessary material.

**********!

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.

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.

After having heard horrible reviews about Jaffe I went into the class with low expectations. I am happy to say that I think Jaffe has made great strides towards improving his class, and I honestly disagree with a lot of the reviews I’ve read previously. I didn't go to lecture a majority of the time and I am still ending the class within the A/B range. I read horror stories about tests but was pleasantly surprised by how manageable they were, and Jaffe allowed us a cheat sheet (front and back) as well as gave us all the required formulas. The workload is manageable and the class isn’t too fast paced; modules are generally quite helpful. The one thing I will say is that it is difficult to follow the lectures if you don’t already know the information on them–if you know the information prior it is helpful so read the book and do the modules before class. Use the text and personal trainer for practice. The one thing I will say is that the TAs were absolutely horrible (I had Bufford and Kadambi) Section was rarely helpful, and furthermore they had an absolutely unapproachable air to them, thus I never sought outside help. Every review session I attended was dreadful, as it was unorganized and oftentimes the information was incorrect. There was a 50/50 shot of the BASIC CALCULATIONS being wrong. Then when students would raise their hand to point out a mistake it would create the utmost hostility.
Regardless, do not let reviews of Jaffe freak you out... He's a really cool guy and not a bad professor at all who IS taking steps to improving the class (new TAs would be great). Overall I sense great improvement.

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。

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!

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.

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.
