really nice man, you can tell he really enjoys stats. easy homeworks and midterms!
Cool guy, very helpful. Knows his stuff. Really easy tests. Has an accent but can still understand what he's saying. He explains everything in lecture in like 10-15 minutes. After that you can just bounce if you get it. What more could you want?
Very nice teacher! He explain the material clearly. Highly recommened!

You don't really have to go to lecture because he just goes over what's in the book. Just go if you need clarification. Other than that, he's very accesssible for help. Easy class.
Easy course, easy tests and homework. He is pretty clear and is one of the funniest professors that I've had. He made a 9am class enjoyable. It's an easy, fun class...take it.
NO OPEN NOTE MIDTERM .. only open note final (3 pages of notes max) NO OPEN BOOK AT ALL.
Very good class. Too bad I had to sacrifice this class and drop it because of my excessive units.
Easy class. Nice professor. If you need this course, take it with this guy.
Easy buy HELLA boooooooring!
Great professor! Make sure you go to lecture though because he will emphasize certain things more so you can expect to see those topics to be on the exam. Also, he'll tell you what you do and do not need to know. Good lecturer. Just make sure you read the book and go to class.
Easy, boring class. He allows cheat sheets for exams (one page front & back for MTs, 3 sheets for the final). Good to go to lecture - he explains things more clearly than the book. Nice & funny guy.
horrible teacher, probably the worst i have ever had at davis yet, writes too small for you to even see, doesnt explain anything, and OH are a joke, its like he doesnt understand english! horrible!! and def not easy even tho it should be
Now, now. His English is not that bad. An accent is definitely noticeable, but it isn't something that hinders the message from coming across. He teaches well, his exams are clear and easy for the most part, and his practice midterms are similar to the actual ones. If you think this guy's accent is bad, you obviously haven't seen (or heard) much.
Good God, His english is not bad, you can certainly understand what he is saying. The class is very difficult, but we are in college. The people who had a hard time understanding him probably sat in the back and dicked around. To the person who keeps referring to China - you are an **** and your probably going to fail.
Seems like a nice teacher, but hard to understand and doesnt explain what he's doing on the board well. Learned more from book than him. Tests were okay, but u need to know how to do every problem or ur screwed. TA's were unhelpful and hard to understand as well. Take another Stats teacher if possible unless if u prefer self-study.
while professor had good intentions, he was very unclear and i felt like i had to self-teach myself often. ta's were very hard to understand and not very helpful. even though he made practice exams, i felt as if the real ones were tough. maybe he just had a bad quarter, but i would reccommend someone else.
The professor is easy to understand and is willing to answer questions. I found the class to be easy, but things are easier the second time around. However, I felt that the projects were a waste of time; although useful if you are planing to do any kind of further studies. Over all I'd recommend him.
This guy is really boring. I never went to class and I learned everything myself from reading the book. Easy midterms and final. One homework assignment a week with only 6 problems. Discussion is worthless because his t.a's don't speak english. Discussion doesn't count towards your grade. Nice guy though not very organized. Easiest class at Davis.
he is not helpful at all. Don;t take him.
he sucks, but he tries to create interest but in the end, he still sucks. There is no reason to go to lectures. When i studied for finals, i learned more myself in 40 min than 5 of his lectures.
Very enthusiastic professor. First midterm was super easy 2nd and final were pretty hard. DO the hw and you'll do fine. Test questions were exactly like hw questions
The lectures were great, Very clear. His accent was hardly noticeable. Those of you who think his accent is strong, you must be freshmen and will have a difficult time later because it gets a LOT worse. The projects were a waste of time. Definitly do the hw test questions were a lot like hw. Second midterm and final are much harder than the first!
Barely ever available for office hours. Doesn't know english and when you schedule for an appointment he will not show up. Oh yeah, he sets the grade cutoffs rediculously high to accomidate the cheating in his class
The booked used for this class really suck making his lectures more difficult to understand. First midterm was super easy though the topics were very hard. Final was a bit harder. Have I mentioned the book suck and every time I see it I want to rip my eyes out?
He is extremely smart - homework is extremely hard, and yet his exams are not at all difficult. It is not hard to do well in his class if you pay attention to the concepts - it's all theory and no math in Jiang's world of regression. Do no expect him to be helpful in class - but he is very friendly and responsive to questions...
VERY SWEET GENTLEMAN. VERY COURTEOUS AND HILARIOUS!
His tests are easy, as is the class, but he is not very good at explaining things. I wouldn't have known what he was talking about if I did not already have the equivalent of Stats 13 from transferring here. Class is pretty boring, he can be funny at times though. Luckily the book is pretty clear.
One of the most boring classes I've had so far. Not even 1/5 of the students went to class b/c it was nearly useless! 1st midterm was easy (96% AVERAGE) but 2nd midterm and final were much harder. Take the HW and projects seriously as they count for 20% of your grade! Old stats websites exist online for extra homework/test practice and solutions!
I fell asleep 90% of the time and always skip the friday lectures. Boring as hell, but the tests are easy.
Jiming is very knowledgable and enthusiastic about the subject. The exams were easy. Weekly homework assignments were a hard and time consuming, and it was a pain that we were expected to use a trial version of Minitab for homework assignments, and there was no lab to explain how to use the program. I didn't care for the book. Nice guy though.
Terrible teacher! I got a C+ in this class and could not tell you one thing I learned. Prof. Jiang is a nice guy but he has no clue how to teach. He never once worked out an example for the class He expect you to be highly skilled in computer programming just to complete the weekly homework. I reccomend you DO NOT TAKE THIS CLASS!
This class was super easy. Although Prof Jiang covered the nitty-gritty derivations of the formulas during lecture, you're not expected to know them. ALL the examples, hw problems, project problems, how to use R (great program btw) etc. were covered during discussion. So go to that (very important that you do!) and you'll have yourself an easy A!
Coming from an otherwise straight-A student, DO NOT take this class! He didn't do a good job explaining anything, and it seemed to be expected that students coming into the class have extensive statistical knowledge. The homework took hours, the textbook was incomprehensible for a non-math major, and the projects require programming knowledge.
He used a lot of book examples to clarify calculations that we need know, although his lectures doesn't fully cover what we need to know. He often just provide general formulas. We get practice exams and notesheets, so make sure to take advantage of those. 80 % of the test materials were what we expected. His homework is quite time consuming.
Okay class. However, he expected the class to know some programming, which I found to be very difficult. Assignments were time consuming.
Weekly HW assignments and MT/FINAL. Practice exams resemble test, allows you to use a page of notes. Expect to put in extra effort, Prof Jiang's lectures are very hard to follow. Would have struggled mightily if not for easy class structure.
The weekly homework assignments were pretty challenging, but the exams were very fair. He provided sample exams for the class. They were good for practice, but the actual exams were a bit harder. Lectures were sometimes difficult to follow, so there was lot of independent studying for this class. The TA was very helpful for this course.
The professor definitely knows his statistics, but is not a great instructor. Like what others have said already, it's really easy to get lost in his lectures. I learned more from the book than going to class.
Knows stats well but sometimes randomly tangents off on useless proofs and skips topics to make us self-learn. Homework is time consuming and repetitive but easier with SAS. Midterm and final definitely had trick questions, and deviates a lot from practice exams. Prof. and TA doesn't always grade consistently across all students and no regrades.
The lectures are hard to follow, homework is mostly based on whether or not you know how to use R. Tests had many questions that did not parallel the homework or lectures. TA was pretty unhelpful also.
He's definitely not the best lecturer. His lectures are not clear, and he goes over important concepts way too quickly, so expect to study a lot on your own. The midterms are fair, whereas the final is a little bit more difficult. If you know how to use SAS and have access to it, use it for this class (better than R, in my opinion).
Lectures sometimes clear, but not all topics were covered with equal depth. Important topics weren't emphasized. Midterms were fairly easy, but final had some unexpected or unseen materials. Recommend to use SAS for homeworks and project, since it's more powerful than R and is what the textbook uses. Overall the class and professor could be better.
Prof. Jiang clearly knows his statistics, however it was hard for me to actually learn from him. There was not enough practice problems solved by him (too many book examples). I had to self-teach the majority of the course. His midterms and project is fair.
Literally the worst professor in the entire world. Do not take this class unless you plan on learning the material on your own time. You can't even understand what he is saying 80% of the time, and accents are never usually a problem for me. Take this class with another professor!
Not a great lecturer, but really nice and helpful in OH. MT1 will be piece of cake, MT2 and final much harder. Weekly HW and group project help your grade (15% each). Plan on learning from the book, basically.
Lectures are confusing, don't go to class and study from the book. Tests are easy, final project and homework worth 15% each with 2 homework dropped. Go to the class a lecture or two before MT day and he will give a summary of what you will need to know. Page of cheat sheet for each MT, 3 sheets for the final.. front and back.
Lectures okay, mostly straight from book. Pretty funny though, keeps it interesting. Need to learn from book on own. Homework very relevant, helps a lot. Project is pretty easy. 15Proj/15HW/15MT1/15MT2/40Final. Grades pretty easy. Final/MT2 much harder than MT1. 1 pg notes both MT, 3 pg notes final. Don't need to go to class.
His lectures are kind of confusing. Since he teaches from the book, just study that instead. The exams are fair and similar to the practice ones.
Class was spent solely on examples, never concepts. Expected us to know what was never taught. Disorganized while writing and explaining. Avoid if possible.
Good instructor. I like his class. Her notes are good.
He's very smart. Great lecturer, very helpful and explains examples well. Course materials aren't hard. Weekly homework assignments are very helpful as well.
I had an amazing TA so the class was a lot better than expected. Weekly homework. The first couple of weeks of the course is super easy. After the midterm, it gets super hard. TA gives sample problems that are similar to homework which is useful. Midterm was a lot more easy than the final. Jiang has neat handwriting but he writes all over the board
Jiang is amazingly helpful after class, in office hours, and if you make appointments with him. Post-midterm, the class began to feel rushed though, with minimal examples (not including discussion). The final was certainly more difficult and involved than the midterm, but it was curved. Would recommend Jiang for any statistics course.
Lectures were close to useless but class was extremely easy. Just read the textbook and study the subjects that he tells you will be on the midterm or final. No surprise questions, everything is generally straightforward.
Very easy grader. Doesn't give too much feedback. Very receptive to questions. Posts helpful lecture summaries. Assigned homework was a good learning tool. Unfortunately, the lack of feedback on projects and a trivial midterm makes you come out of the class questioning how much you actually learned even with a high grade.
The class was generally straightforward. And the weekly homework was helpful in understanding the material(the TA helped a lot during discussion). Generous curve overall.
To be honest, he's not a great lecturer; I mainly relied on his lecture summary notes. His exams are pretty straightforward, just look at the summary notes. First midterm was easy, but the final was tough. He's a nice guy and super receptive to questions!
He lectures material too much from his own research topics. Also, his lectures are from projector slides so it's kind of dull. Grading was easy because of TA Po. Final project very long
Horrible professor. His exams are tough yet he doesnt lecture well or give enough relevant example problems. His TAs are lazy and dont even bother to try hold a decent discussion.
I really like Professor Jiang's class. You can tell he's passionate about what he teaches and research on from his teaching. Class is very well-organized and full of examples. I personally like his way of teaching by giving a lot of examples because it's much easier to understand a new concept. Midterm 1 is easy and the average is 80+.
He tries but is not a very good lecturer. Class had only one midterm, 2 group projects, and weekly homework assignments.
He is an ok professor. Not the best lecturer, but he tries. One midterm and two group projects. BEWARE OF WHO YOU PARTNER WITH ON THE GROUP PROJECTS because they can make or break your grade on them. Easy midterm and final just be sure to study. No curve since averages are too high.
He is a very caring and generous professor. His lecture is simple, but we need to pay some time study after classes. One Easy midterm and a hard final. But he is an easy grader.
The class was okay, professor is good and tas were also good. The reader in this class was a tough grader though. Two group projects, weekly HW, one midterm, and one final. Midterm was supper tedious thus being tricky b/c of the time constrain. Final was a bit tough but doable. Group projects and HW were relatively easy.
Jiang is funny, caring, and always stops whatever he is saying to answer your question in class, then picks up where he left off without skipping a beat. One easy midterm, one final (ours was cancelled), two easy projects-provided you pick a good partner- and weekly homeworks. Best professor I have had at Davis! Highly recommend.
It pains to write this since I liked the class, but I need to voice how unfair the covid19 grading situation was. The class is a joke and everyone gets an A, but since there was no final, he curved down by 5 percent, implying that only a 98 or above is an A. It was super inconsiderate in the midst of a pandemic, and despite having a 95 I got an A-.
Professor Jiang is super caring and accommodated the class to virtual learning really well! The lectures are well thought out and well paced. The assignments and exams are really similar to the material covered during lecture (usually). The grading is also very generous as lots of partial credit is given on assignments and exams.*
The course is not hard and the professor explains everything clearly. You can also review the lectures(materials) through the codes in discussion and the homework.
Great teacher. Grading can be rough at times, but I think he accounts for it in the final grade cutoff. Lectures are quite helpful and he's really happy to answer questions. Prof. Jiang & his TA were forgiving during the exams on multiple levels. Definitely one of the better professors in the stats department at UCD, I highly recommend him.
Really good professor. His lectures are fantastic especially since he's one of the few to actually give written examples. 7 homeworks with the lowest 2 dropped. 2 easy group projects using R. 1 easy midterm but a pretty difficult final. Good curve and overall one of the best professors in the stats department,
I came into this course with no stats background and it was pretty rough. I feel like the lectures did not explain underlying concepts that well and his lecture notes were not very easily understood. I relied on textbooks and TA's discussions to do all hws and study for tests. Tests were a bit tedious but fair, they are weighed heavily though.
Pretty easy class and learned a lot. 7 homeworks, 1 easy midterm, 1 difficult final. Great lectures as well.
Professor Jiang gives clear and detailed lectures and easy assignments with generous grading criteria. Sometimes there may be exception, but it should be acceptable.
Lecture was a bit bland, but he did have his moments of being unexpectedly funny. All the lecture notes for the course are uploaded at the beginning of the quarter. Not super difficult, but definitely a bit boring.
The whole class is disorganized. I don't know why he has such a high score but RUN if you have only taken sta 13 before. Seems like he assumes everyone knows a lot about statistics. He never explains what the new symbol comes out stands for, mostly you have to google it or search from the book.
He's a good lecturer in all honesty this class will be tough if it is your first time doing upper division Stats. I recommend you do some review of Statistical concepts before taking this class. Learn some R studio too because you will need it in class to do the homework. He post lecture summaries and recorded lectures so you can catch up.
Nothing you learn from the lecture is relevant to the assignment. The assignment is all about R code but he asks us to print that out and submit it in class. The discussion handout probably helps a little with your homework but don't expect TA will explain those codes to you. I really don't know how he got such a high score here.
Absolutely the worst professor in UCD I've ever met!!!!!! The whole course is disorganized, every class I just sit there listening him read concepts and formula from teh textbook without a proper explain as a university lecture! Luckily, I've took STA 106 which is the second part of the textbook, so that at least I have a little clue of the class.
Reading the textbook is more helpful than the lectures, and the lecture summaries are hard to understand. Why theis professor has a such high rate? You can learn nothing from this class.
Lecture does get confusing every now and then and you may need to search the concepts up a bit further outside of class to understand it. R code is not taught much in class but is mainly presented in discussion sections. The professor overall though was pretty good and had really good enthusiasm throughout his lectures.
Absolute legend! Professor Jiang is amazing, knowledgeable and funny. Very easy to do well in this course if you put in the effort. You my friend, will not regret this class.
I'm surprised by the slew of negative ratings this guy got. I thought he was good. He really tried to explain a very tough subject as clearly as he could and I felt he was overall very fair with what he asked of us. I do wish he could actually go over problems rather than reference the same Toluca problem repeatedly. R projects were tedious, though
No upper div stats class is "easy". He teaches alright and has lecture summaries about his lectures. Read the book before coming to class it helps. For the R portion of the class learn some stuff on your own you'll need it. Overall not an awful class but not "great" or amazing either. Remember this is UC Davis so study on your own to understand.
Professor Jiang is overall a great lecturer as long as you attend the class you will be fine since the lecture summaries might be confusing. 2 main straight forward group project, one easy midterm and one tricky final. Overall very caring, responsive, and passionate over his students and statistics.
Very kind instructor. This is the first high-level course I take at UCD and I survived. His lectures are easy to understand and always have clear summaries on Canvas, making reviews easy. Exams are easier than homework and practise exams are helpful. Homework needs coding and his TA has very good interpretation of the coding topics in R.
Awesome professor YOU MY FRIEND WILL NOT REGRET THIS CLASS.
Homework very long, lectures are good and notes are concise, midterm wasn't difficult, but the final exam will tank your grade. The class would definitely be considered hard, but outside of that I wouldn't really say I had anything outstanding or problematic to speak on the class.
Jiming is a legend! He is a very bright guy with lots of fantastic stories to help motivate the material learned in class. He is a undoubtably an accomplished researcher and most of the material covered in the course is related to previous work he has done. He know his stuff! You my friend are a great teacher!
