STAT 3120

This course has difficult content, especially if you struggled in STAT 3110. The course definitely builds off of the assumption that you understand distributions and basic probability, although Justin does give pretty good overviews to catch you up. While the prerecorded lectures do kind of suck to watch before class, they are really helpful to rewatch before exams. He is generous with partial credit on exams and does not make the exams cumulative. In class lectures really clarify applying the concepts from prerecorded lectures. He is one of the most fair professors and repeatedly reminded us that if we needed help or we were struggling to ask for help early and often. Although this is a difficult course it is worth taking, and Justin is definitely the best professor for this course.

Justin was a great professor. You were expected to watch a ~30-minute pre-lecture async video before class and attend the lecture. The lectures were always shorter than an hour and fifteen minutes. Every word Justin said during lectures was articulate and meaningful. He knew his sh*t. He broke down every concept and made it easy to grasp and understand. Homeworks were not expected, but super helpful. Do them. They prep you for the exams. The weekly quizzes were stupid easy. It's just your lecture notes reworded, but definitely helped you better understand the subject. The tests were weird - definitely buy the textbook so you have more practice problems to go over to prepare for the exams. Half of the test is T/F questions worth 4 points, so if you miss 3 of those, you're already at a B- on the test. These T/F questions were VERY similar to the weekly quizzes. He's really lenient on partial credit. As long as you understand what you're supposed to be doing on the problems, he gives you back points, which was really thoughtful and nice. 100% recommend this class if you like math, but definitely take it with Justin - it's worth it.

You can never go wrong with Justin Weinstock. Passionate about teaching stats; really want his students to get good grades and understand the content at the same time.

I took this class Fall 2021, but it was still online due to spacing issues. This means all our exams and quizzes were also online and open-note, so I'm not sure if this will be applicable for an in-person version.

The grading is 25% quizzes and 75% exams which seems a little daunting but actually isn't terrible. The quizzes are 5 true/false or MC questions that he usually pulls straight from the slides and take less than 5 minutes to finish. He also gives you 3 drops (there are 12 quizzes).

While he doesn't grade the homework, I would still recommend keeping up with them because they are really good practice for the exams. The exams are usually 2-4 short answer questions that are very similar to the homework and a couple of true/false questions. He is very generous with partial credit on the free-response, but you need to be careful on the true/false because they're worth a decent number of points. There are 3 exams and none of them are cumulative.

Justin is an incredible professor. He's really good at making challenging material understandable and is not out to trick people or make them fail the class. He is very patient at answering questions and is extremely approachable during office hours or outside class. He goes through a ton of practice problems and does his best to prepare you for the exams, so as long as you keep up with the material, it is not as difficult of a class as everyone makes it seem.

Such a great class, material covered is extensive but very applicable to job interviews! Justin did a great job of explaining the somewhat dry math behind and using real world scenarios for better understanding. Weekly quizzes on concepts and three straightforward test similar to homework problem, I would highly recommend taking mathematical statistics with Justin!

This was a pretty challenging course, but the way Justin structured the course and the way he lectures is super organized. He's probably the best lecturer I've had for any kind of math-related course. He's also super helpful in his office hours.There's 3 non-cumulative exams worth 25% and weekly T/F quizzes that account for 25% of your grade and the lowest 2 scores are dropped. If you take the time to really understand the concepts and practice the homework and in-class example problems, you'll definitely be able to do well!

Justin is a great option to take this course with. I really liked him and he feels very approachable since he's really close to our age. He remembers 3120 when he took it himself as an undergrad so he doesn't make it harder than it needs to be because it's already challenging. I felt like his tests were hard and I wish there was more assignments that could pad our grade instead of it being all based off quiz or test. I'm a slow test taker and I felt limited by the time limits on the exams. In my opinion, I feel like it'll be hard to get an A in this course but he did lower the thresholds a bit at the end of the course which helped people.

NOTE: I took this in Fall 2020, there wasn't an option for it when I was choosing the semester, so I had to put Spring 2021.

Justin was incredible! His grading scale is 75% exam-based and 25% quiz-based (weekly, and he dropped the lowest 2). He provides optional homework, which covers more application and calculation-based problems, and the quizzes were conceptual and based on the lectures. DO THE HOMEWORK. The exams are extremely similar to the homework.

Justin is a cool guy. He understood that this semester was tough, and he wanted to give us a break, whereas other professors definitely didn't. Exams and quizzes were open-resource, and he provided solutions to the homework as well.

The lecture slides were the biggest help, along with the homework. He worked through problems in class, but he recorded them, so you could always go back and watch them later. The problems at the end of the slides have guided solutions, and would also reflect the exam content.

The exams themselves were 4 sections: 3 mostly computational and 1 purely conceptual T/F with 5 questions (similar to the weekly quizzes, which were 5 T/F conceptual questions), and weren't cumulative. The T/F can be tricky, but if you have the lecture slides with you, you should be fine.

One last piece of advice: Watch the pre-recorded lectures. He says some additional useful stuff about the concepts that aren't in the slides, which allowed me to gain a deeper understanding of the content.

Overall, very good teaching, and I loved this class! It gave a complex and mathematical foundation to basic statistics, and allowed me to understand why we do what we do with hypothesis testing, significance levels, etc.
