Easily the best class and best professor I've had in my time here. Professor Stigler is extremely accommodating and demonstrates how much he wants us to succeed. However, do keep in mind that this class has nothing to do with math and mainly focuses on coding. You don't need to buy a textbook because there is a free online textbook that is broken down into modules that you complete for homework. There were two quizzes that were pretty straightforward and he did allow us to correct our mistakes for the first quiz to earn an extra 5 points. The final involves a dataset that you are expected to analyze and it's pretty straightforward. You will spend the month prior to finals week working on a practice final that is exactly the same as the final but just uses a different dataset. If you have a chance to take professor Stigler definitely do it! I was nervous about this class because I had never coded before but he and the TAs did a great job at guiding us through everything.

Okay I genuinely underestimated how easy this class is. Like I've heard that this is a ridiculously easy class...but like it was truly a free A+. I did not attend a single class and didn't pay attention to the CourseKata assignments and I still got an A+. I literally survived this class solely using high school stats knowledge.

This was easy because the HW and practice final were based completely on completion -- free points. The quizzes were solidly easy because they were take home and open note. And the final was basically the practice final with different numbers.

Statistics is a concept that often goes over my head-- I hate math and coding, and statistics is a good, healthy mix of both. However, this is one of the best classes I have ever taken. The textbook, which Dr. Stigler co-authors, is very, very helpful. It integrates coding exercises with statistical concepts seamlessly, and I always felt like I knew what the code was doing & why I was writing it. In other coding courses, I have often been unsure of what the function of the code I was writing even was, but not in this class. Coding became fun once I knew what I wanted from it-- it became more of a tool rather than something to be afraid of. As for the teaching team, I couldn't have asked for better faculty. Dr. Stigler was extremely understanding and flexible, conducting the class in a remote format for students who chose to & providing a hybrid option for those who wanted to come into the classroom. He has a great sense of humor and was never condescending when students asked questions-- he always opened up the room for students to talk and was very thorough in explaining concepts. My TA's this quarter, Icy & Mary, were exceptional. I really felt that they went above and beyond in providing assistance to students. During lecture, they constantly monitored the chat, never leaving students hanging with a question unanswered. They were often willing to set up extra office hours to clarify any super confusing concepts and provided helpful slides to accompany their lectures during section.

Take 100A with professor Stigler, you will not regret it! He is such a helpful and understanding professor.
Class breakdown:
5 quizzes (every even week): 40%
Homework: 15%
Participation (this is optional, but if you choose not to participate, quizzes and final will be weighed heavier): 15%
Final: 30% (he made this optional!!)
Great professor overall and I have learned a lot from him, and I'm so glad I learned how to use and navigate in R!

Stigler is a great professor! He's the best professor to take Psych 100A with!
I really enjoyed having him and he explains the material really well!
Although I found some of his quizzes to be rather difficult, he drops the lowest quiz and even made the final optional this quarter!
Overall, the class was interesting and I would highly recommend him!

Going through the textbook chapters for homework can be tedious, but it isn't too bad. There are open note quizzes every other week (untimed, essentially 24hr) and the final was also open for 24 hours. Attending lecture was not mandatory, although extra credit was given if you did attend and fill out the Jupyter notebook for the day. Overall, Psych 100A is a pretty easy class (even more so if you've already taken Stats 13) and the coding isn't that complicated. Stigler is a very understanding professor whose teaching is clear and straightforward, and I recommend taking this class with him!

Amazing professor and class. Everything is spot-on. However, Stigler can sometimes struggle to deliver a certain concept in a clear and concise manner. Otherwise he's extremely accommodating and attentive.

Study tips: take DETAILED notes on Jupyter while paying EXTRA amount of attention in class. His usually tests only on concepts covered / emphasized in class. Obviously the HW is also important, but it's way too time-consuming to go through entire chapters to review for quizzes.

Stigler is a super chill professor! I came into this class with no statistic background at all and I was able to do well in this class. The textbook is embedded in CCLE so you don't have to buy anything! There are also some videos that help break down some more theoretical concepts. I would 10/10 take this course again with him.

I love Professor Stigler and his Psych 100A. This class is easy because Professor explains materials that are tested clearly during lectures. After taking this class, I feel like I am prepared for R coding and future Psychology researches. Taking this class with Professor Stigler!

Overall, I enjoyed taking this class with Stigler and the two TA's: Laura and Mary. Stigler is very patient and understanding, maybe even to a fault (because people will abuse the anonymous online questions form and ask for clarification on things that maybe they should have asked about in person rather than wasting an entire lecture of 200+ students' time). However, I appreciate the time he and the TA's take to make sure that everyone understands the material.

The material for this class is based on the free online Canvas textbook. Exercises are due weekly. And the amount due each week varies, so pace yourself. In addition, the homework exercises are graded on completion (thank you so so much). This quarter we used the program jupyternotebooks, which is where all the coding practice and quizzes are submitted. This class uses the programming language R and you will be given a "cheatsheet" of sorts, so there is no heavy memorization in the class. Most importantly, you will be tested on application and understanding of the concepts behind the code you write.

There is no midterm for this class, so grades are primarily determined from the biweekly coding quizzes and the final. There are also extra credit opportunities. Honestly, it's an easy class as long as you take the time to understand the homework (but also try not to let yourself get caught up on the convoluted explanations the textbook gives).
