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.

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.

I came into class with low expectations after doing extensive reading on Jaffe's negative reviews on here. However, this class really isn't as bad as people make it out to be!

Your grade is broken down as follows: 30% Midterm #1, 30% Midterm #2, 30% Final, 10% Quizzes + Participation (completion of modules and in-class questions on Top Hat and CCLE quizzes, which you get 2 attempts on, and for which the higher score is counted in your grade). The first midterm was extremely easy, the second midterm was harder (the time constraint and more conceptual than calculation questions really killed me, but they ended up curving the test), and the final was somewhere between the two. He gives you a formula sheet and you are allowed an 8.5 x 11" double-sided cheat sheet for each of the three exams.

I always did all the modules as soon as they were released on Top Hat, and in class, even if you don't know the answer to a question Dr. Jaffe assigns, make sure you at least submit an answer (anything!) in order to secure full participation points, because *sometimes* he will close a question and you can't answer it again at all later on, and then you'll have lost an easy participation point. The quizzes are no sweat either, since after you submit your first attempt, it'll show you what you got wrong and right, and what the correct answers are (so there's really no excuse for scoring less than 100% on each quiz).

I never did any practice problems outside of what was assigned on Top Hat and in class until about a week before finals, when I reviewed Top Hat problems and looked up online practice problems on the topics that I specifically didn't feel the most confident in. I don't particularly recommend this, but if you are busy with other classes then it's still possible to get a good grade without doing tons of extra practice and work for this class. I also did not purchase the online resource that you could get with the book (I forgot what it was called) and I did just fine using only the physical textbook and Top Hat.

Dr. Jaffe is a really nice person and if you go to his office hours he will definitely try to help you out! He tries his best in lectures, but they're not always the most engaging. I do think part of the dead atmosphere in his class is due to the students as well -- we almost never participated in class (he would ask general questions for which we should raise our hands, and less than half the class would).

Jaffe, as a human being and as a public speaker, is wonderful. Hands down one of the most genuine, fair, charismatic, and caring professors. That being said, he cannot teach statistics in ANY capacity. This class was GRUELING and the entire time, I wished I had taken this class with any other professor. It was 1000% self-taught, all lectures and discussions made the material MUCH more confusing than it needed to be, the required purchase of TopHat was the worst implementation of technology because it had errors ALL the time and were just as unclear as his teaching. I studied and annotated the entire textbook, went online to reviewmaster, took practice quizzes, did practice labs, studied his slides, went to AAP sessions, had a private expensive tutor, and I still BARELY received a B (this course killed me). The exams themselves are not intended to be tricky, but they skip over some main conceptual ideas and make the questions too difficult and with so many errors. If you can, take it with any other professor. Do not compromise your gpa by taking this class, you won't even learn anything that will be remotely helpful for 100B or even your academic career in general.

When I first enrolled in this class I was feeling almost desperate because the other 100A was already full, but it turns out that this class is really different from the bad comments from bruinwalk. Dr. Jaffe is a really cool professor who really wants to communicate with students and tries really hard to explain all concepts. He is really really approachable and would keep explaining one concept until everyone feels okay about it. He has a textbook which is really overpriced. I never read that book and relied entirely on the module and still got an A+. His tests are all really easy, especially if you have taken stats classes before or have basic understanding of hypothesis testing and probability. He allows students to have one cheat sheet and curves the scores whenever needed. Overall, I'll rate A- for this class and A+ for Dr. Jaffe.

I highly recommoned Prof. Jaffe's class if you are planning to take psych 100A. He is charming and funny which make the lecture not boring at all. He also explain the material pretty well, but make sure you are familar with all the formula before the exam.

There are three midterm total (90%) and online quizzes (10%). And the quizzes are due every Friday.

Hope this helps :)

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.
