overall extremely easy course !! there is a language barrier but all notes are typed... good to go to class because he clarifies it but not manditory ! labs are super quick ! like 15 min...if your study and practice a bit and do the assignments the tests and quizzes are a joke !! this prof is muccch easier than the other one and marks easier !!!
Haiyan is a really nice guy, and his online powerpoint notes are pretty comprehensive, which is good because you can't understand a word he says. Even with the language barrier, he gets the material across pretty well. Avoid if you are a "listening learner;" you won't understand a thing.
it takes at least 3 lectures to be able to understand him, after that it is fine. he is really concerned about students and is one of the nicest profs out there.
Very hard to understand him. Although he is a great professor, and wants to help everyone understand its so hard to understand his language
Excellent Prof! A little hard to understand but very sweet man. He will help you out with anything and is also very lenient. This course is an easy A if you do the work. But the labs are pointless and missing them will not affect you in the least little bit
Haiyan is a great prof. His notes/ slides are good- with worked examples of most examples done in the course. Course material is fairly easy as well. However, his english is quite hard to understand, so it makes the lectures difficult.
great prof. Easy course, just do the assignments and practice questions from slides and you will get an A.
Very hard to understand at first. Course isn't hard if you attend class and go through slides...no need to buy textbook. Haiyan is sweet and genuinely cares about students!
Dr. Yang is an excellent professor. His accent is pretty hard to understand at first but once you catch on it is clear that he is a genius. He shows a great passion for what he does and that makes it easy to listen in class. His assignments/tests are very straight forward. However, the lab is absolute garbage and the quizzes are torture.
Despite what others have said here, I currently have this prof and find him VERY hard to understand. He is willing to help but has difficulty communicating course content. I hate going to his class but I go anyways. There is an attendance sheet. The labs are probably the best part of the course.
he was great prof, little hard to understand. But he has great slide shows and notes to make it easier.
This is the worst class I have ever taken. I have shed tears IN CLASS because he is so insanely difficult to understand. He talks very fast with a very thick accent and he only explains the concepts, never gives examples. I figured I used get used to his accent but I did not. Pro tip: he says probability as POBEN. Good luck if you take this class
hard to hear and understand. Uses lots of examples but doesn't finish the solutions and leaves out the answers.
By far worst prof Ive ever had, and Ive had a few bad ones. First of all, hes nearly impossible to understand, while not his fault, it definitely isnt fair for the student. What is his fault however, that he didnt cover all course material, and much of what was covered is done with different tables and formulas than what he teaches.
It is easy to follow along in his class even if you do not know exactly what he is saying sometimes. All you really need to know is "par bench"probability. EXCELLENT notes and he does so many examples and practice questions in class with you, so if you follow along and write down everything he puts on the board, you'll be fine! Midterm was easy!!
Assignments were fair, notes were helpful and his slideshows are great. Might have to do some work outside class to finish up examples, but he does give you the steps and point you in the right direction; (it is university afterall.. you can expect to do some work!) His accent is thick but he gets his point across if you pay attention!
Dr. Yang was a fantastic prof, very caring if he knew you were showing up and doing the work. I would recommend not missing any classes as they are helpful. The language barrier is a little hard at first but after 2 or 3 weeks you get used to it. Sweet man, very eager to help you and have you pass the course. In class he will narrow down midterm.
Yang is an extremely good prof, and it is clear to see that he knows what he is talking about. The only issue I had with him was that the language barrier made things very difficult. However, if you go to every class you will begin to understand what he's saying and it gets a lot easier. He is also super nice and cares about his students.
He is pretty hard to understand, read the chapter before taking the class, it will help to understand him better. One thing I found was that his notes are pretty good (straight out of text), however his tests (midterm, final) were extremely hard. Way harder than any of his examples in class and harder than the practice questions that were given.
Yang is quite hard to understand. I did not understand much of his explanations in class but once he has solved the problems you will get it. He is really caring to his students, he wants everyone to pass.
I barely went to class since I found his accent impossible to understand. I went to his office to get a midterm back; I got a 48% and he literally gave it back with a smile and said "not too bad" and asked me to come to him if he had any questions. He may be difficult to understand but he's so pleasant, kind, and he really wants you to succeed
Only take this course if you can learn from only reading sparce lecture slides. Very nice to talk too if you can understand what he is saying
He is an incredibly caring professor however he is INCREDIBLY hard to understand. However if you can teach yourself using a textbook, Google, and lecture slides, you should do okay.
Due to the professor's very thick accent, he is extremely difficult to understand. I had to teach the majority of the material to myself. Please avoid this professor.
He is a good professor but understanding his accent can be a really big challenge. Once he writes down the answers on the board stuff makes sense but need a lot of practice. A lot of material is covered in a single class so missing one can make it harder to understand the next class. Lectures will also get very boring soon.
If you go to class or dont. doesnt matter, you'll fail anyways. he talks gibberish. Does he even english bud?
Dr. Yang was great prof, little hard to understand for the first week and you get used to it. But he has great slide shows and notes to make it easier. He was a fantastic prof, I would recommend not missing any classes as they are helpful.
attend class, review notes, practice more, well done.
practice questions are quit useful in class.
He gets a bad rep because of his accent but you get used to it after a week or two. He's very kind, gives practice questions in class and uses slideshows and examples to help you understand the content and what he's trying to say. Everything is posted online but you really need to be there to understand everything for this course.
Professor Yang is a funny guy, and a great professor. He does have an accent, but it's very easy to get used to quickly. His lectures are informative and well organized, and he's always willing to answer questions.
Dr. Yang has a very thick accent, I found him very hard to understand. He does not use the textbook so he tries to explain things well, but his accent makes this extremely difficult to understand. He seems to really care about his students' performance, but he is definitely not the best prof for this course.
He seems to care about his students, but he removes answers from the slide shows so you have to attend the class to get the answers to his slides. But he doesn't make the slides so answers can be found online, but he seems to remove them to make it harder on students who can't make it to class. His Lab quizzes are 20 questions, other class is 10.
Its only people who give up after the first week that really do bad in this course, its simple math. He Is very helpful during his office hours and gives exact examples in class that are used on assessments, if you go and actually try you'll do perfectly fine! The language barrier becomes no problem after a few classes and evaluation is fair/easy.
Grades very fair, he is very hard to understand but is probably the best prof you will get for stats, I personally struggled with the course but he is very caring and willing to help. Exams and quizzes are all multiple choice which is the only thing that helped me get through this course.
His accent was kinda hard to understand but once you get used to it it will be fine. You just need to show up in his lectures and you will get a really good grade.
One of the worst profs ever. Doesn't know how to pronounce/say basic English words even when he's using the textbook to supplement his thought process. And when asked questions he speaks an alien language that stops students from asking further questions. Avoid his classes like a plague.
Regardless of his accent, his remote lectures are disaster. All he does is reading from the slides and 'rarely' shows examples. Also the slides given are very poor. Had to take his class since I need to finish this course before the fall semester but try to avoid him if you can.
He is a great prof who genuinely cares about his student's success. Also, his tests are multiple choice questions, which was nice. Highly recommend!
I had to take this course online because of COVID, and Yang does NOT make it easy. He answers emails with the bare minimum response & his quizzes have the most difficult wordings for a simple question. For the first week of the course, he didn't even make one announcement to let us know if the online classes were going ahead or not. Don't take him.
Super hard to understand with the accent but you eventually get used to. Replies to emails quite quick
I have Khan Academy to thank for passing this course, the entire course is explained much clearer there
Dr. Yang seems to care about his students, but also does not seem aware of what is going on in this online course. He has given conflicting instructions for the final exam, which is worth 50% of the final grade. His lectures are difficult to understand, so you will likely be teaching yourself. He uses a free textbook, though!
he is an amazing professor, this course was super fun to take and it was easy for me.
The course structure and designed by Dr. Yang was very convenient and helpful for us.
His English accent is so bad and he goes extremely fast through the material i can barley understand this guy. Don't ever take a course with him online
As a perfect GPA student, I thought this would be a walk in the park. Damn was I wrong, stay away from this prof at all costs, his accent makes his lectures unbearable, you will not learn anything in class. Labs are the least helpful unorganized things out there. If you take this prof expect it to be a self taught course.
Haiyan is a really good instructor. His accent may be a little difficult to understand at first but if you pay attention, you can catch on really quick. He is super nice and very open to questions and giving extra help. Take notes and study them well. I didn't buy the textbook and I got an 86.
A little hard to understand at first but was fine after a couple of lectures, and the lectures are not mandatory as long as you read the slides and do the practice. Easy exams, he reuses the same questions on midterms and finals. Replies to emails very fast! As long as you do the practice, it's not hard to do well.
I hated the course, its so hard to understand what he is saying he just go over the slides with no good explanation. i would never advise anyone to take it with him. he is very nice replays to you email fast but very bad at teaching.
Absolutely incomprehensible. Played his lectures for a few other people and not a single one could understand one single word from them. Useless. The labs are just as bad - the only "answer" I ever got from the lab instructor was, "Wow that's weird, it works on my computer." Shame on MUN for expecting people to pay for this *required* class.
You cannot understand what he speaks, cannot understand what he writes in notes, and does not give any opportunity to increase grades. He is a tough grader with major weightage to the final exam, which is most difficult being cumulative. Do not take him, save yourself.
Professor Yang is not good but also not terrible. His accent makes lectures unbearable, but the weekly quizzes, midterm, and final are straightforward. The issue is the weight for them based on the number of questions. 15 MC on the midterm is worth 20%, and 20 MC on the final is worth 50%. I'd walk into my finals with a strong average.
Pretty bad, his accent and teaching is not good at all only one hour a week as well and doesn't really explain anything. I basically had to learn the course on my own using his lecture slides. However, he does grade by the curve which is what saved my grade tbh. I might like Stats idk yet, but not from this professor. Hopefully it gets better
Exam Questions are not covered. Labs are horrible. The lab assistants do not know the R platform. I cannot believe MUN is charging for such a horrendous course and poor instructors. I have dropped this three times while waiting for a good instructor. Still waiting.
Just a rough course. Impossible to understand the prof or the lab instructors at all. The quizzes were not the hardest things in the world, but the midterm and exam made you work for it. Would not reccomend!
Professor Yang has an accent that can be hard to understand. I highly highly highly recommend going to class in person because the online lectures are near-incomprehensible due to his accent and audio quality. The exam is HEAVILY weighted. However, he is fun and goes over material a lot and has many examples in the lectures. I recommend him highly!
This course was extremely difficult. Our final is only 20 MC, worth 50% of our grade. so many mistakes were found in the mini-quizzes, making it difficult to study for the final. Do not recommend taking this course.
Worst prof I've had in my university career. He's impossible to understand and he doesn't know what he's teaching. He tests every week and grades them improperly; 90% of my tests had at least 2 grading errors on them (and no he won't fix them). The exam is 15 MC and 5 multiselect questions but worth 50% of our grade? You're set up for failure.
Horrible lectures that just confuse you. Weekly quiz material is random and information not covered. Midterm and final exams are confusing and really hard. Avoid him a tall cost.
You won't understand his lectures because of the accent but most of the time, the lectures weren't necessary either. The slides were good enough, and the questions were relatively straightforward. He is also very helpful in e-mails and tutorials.
Very poor teacher. I did the two lectures per week and read the chapters then went to YouTube for better instruction. He covers some very basic questions as examples then uses much harder variations for quizzes and exams. It was a horrible experience which is sad because I actually enjoyed the material. Good luck to any student that must use him.
Dr. Yang's course for guiding me as I re-experienced R and I could not have wished for a better teacher to do it. Thanks a ton for this semester. This semester passed by way too quickly and I hope it was as fun teaching us as it was for us learning.
Dr. Yang give us lots of interest questions in class, I love this course.
I couldn't understand his pronunciation and the teaching style wasn't fit for me. I was able to pull off a B , just because of the tutor(Kismat Ghimire) so if you have to take the course just hire a tutor and get rid of your headache
Very helpful professor. If you study hard you will do good in his class.
Yang was a good guy but average teacher. the course content is difficult, and I felt he didn't go over it in enough detail. midterm/exam were very fair, and questions were reused from quizzes/slides. Utilize rstudio (very straight forward) and youtube videos before class. attendance was also taken.
He is a very nice man, but the language barrier is impossible to overcome. Had to teach myself this entire course since I can't understand a word he says. MUN please hire English speaking profs. Seven quizzes worth a total of 30%, 1 Mid-Term worth 20%, and the final worth 50%.
Honestly, Dr. Yang seems very nice, but I couldn't understand his accent at all, so the video lectures were no help. Luckily he posted pdf notes, and the textbook was helpful. The sample questions were nothing like the exams. The sample questions were usually long word problems, while the exam questions were very short with almost no details.
Obviously, the familiar knock on Dr. Yang is the language barrier; not a lot of information can be taken from lectures. The lecture material he posts lines up directly with questions on quizzes/exams, sometimes even direct repeats. If you work to learn the material for the quiz every week, you will have no trouble succeeding in his course.
Dr. Yang was completely absent, I didn't even know what he looked like until the midterm. His online lectures were useless (if you could even understand his accent) and he grades quite harshly. I do not feel that I actually learned any of the material in this course.
Dr. Yang is a very nice and approachable prof. He emails back within an hour. However, his accent is very hard to understand. I attended a few lectures but I couldn't understand much and was wasting my time. So i only went to the quizzes, midterms and final.midterm/final are fair, he usually repeats a few quiz questions in the exams.
contd from previous review. Lab instruction for this course is pretty useless too. Its just a time allotted to do quizzes in person. The lab instructor barely taught us anything and even then it was a struggle understanding her because of her accent.
The main issue was his accent. He's a nice guy and replies to emails quickly. The midterms and finals are similar to slides questions and quiz questions- practicing those will be helpful.
Posts great notes that tell you everything you need to know to pass, however, if you are a student who requires verbal teaching good luck. Accent is genuinely impossible to understand and as a result, there is 0 purpose of going to class. Make sure you go to labs as this is where tests are held
Taught myself the whole course with the help of a tutor due to the language barrier with this prof. Did not attend any classes as I was unable to understand him. Weekly quizzes and midterm were very fair, however I found the exam to be more difficult. Does not provide any practice questions which is crucial for learning a math course.
I had the course with this prof and TA moein yoosefi and I can confidently say a third world country may have better professor and TA's. The level memorial has stooped to save on paying for good TA's and professors is embarassing. They both speak completely wrong English and teaching style is very disorganized.
You can't understand what he is trying to say due to his accent and poor English. Only reason I am doing good in this course is due to Kismat- tutor I hired. Recommend self studying, getting help from youtube or hiring a tutor if you need to take him. There is no point in attending his boring lectures
He's willing to help you with any problems. Replies to emails in a snap. He has a super strong accent but understandable. The quizzes and exams are super similar to the practice problems he'd solve during his office hours. Overall, it's a moderate experience.
While dr Yang is caring and wants to help, Stats is hard and the Online course structure is difficult to follow. Also, half your final grade is based on 25 multiple choice questions. Get comfortable with R studio and consider getting a tutor.
Unfortunately Haiyan Yang cannot carry on a conversation in english. It's extremely difficult to understand anything he says. How he ever received tenure is beyond me. Admin has known about this for years, yet has done nothing. I'd recommend that you do an online course with a different university instead, and transfer the credits.
I had to take this course bcoz it was mandatory. When I read the reviews at rate my prof, I was so scared of this course. After taking this course I will say the prof is definitely really great. The course material itself is really hard and you need to understand stuff properly. He is caring and if you do his pratice q, it is an easy A. Great prof.
Haiyan Yang is probably a nice guy... however, I'll never know because I cant understand a thing he says so I'm not sure. His midterms and quizzes are fair but you'll need to teach yourself everything because you won't learn anything in his class without minoring in mandarin.
Good luck understanding him and his thick accent. Stopped going to lectures after first few weeks and hired a tutor-Kismat to teach me. The midterms and finals are very fair tbh and quizzes are not too bad either if you revise the chapter questions. Tip: Hire a tutor if you can or visit help centre often and hope someone who knows stat is there
Dr. Yang has a super thick accent which is hard to understand. The examples that he does on the board in class are not particularly helpful either. The exams and quizzes he gives are very fair and straightforward. To do well in this course, I recommend hiring a tutor and teaching the material to yourself. Also, learning to use "R" code is a must.
Dr. Yang is not proficient enough in English to be teaching. I am the only person that I know who did not use AI to pass his quizzes/exams. He is not accommodating at all. He relies too much on R, instead of teaching stats, he mainly teaches R-code. He is not confident in his own teaching abilities. The only positive thing to say is, he is nice.
Even though it's impossible to understand what he is saying because of his accent, he is so sweet. He means really well and is funny. He is helpful, responds to emails quickly, and gives fair midterms and exams.
Although Professor Yang has an accent, it doesn't affect understanding. There is a textbook, but his slides are sufficient for studying. The exams include question types similar to those founded in the quizzes and slide exercises. Professor is very nice, and student are allowed to bring formula sheet into the exams.
His notes were a mess, and theres just too big of a language barrier to get any help. He made STATS so much more difficult than it needed to be. Would never ever in my life take another class by him again
I am normally a straight A's student. I have never ever taken a course where I genuinely believe I have taken in nothing from until this. I normally have no issues with accents but I cant understand him. His handwriting is terrible. His slides are so packed you cant learn from them. Had to spend extra $600+ on tutoring because no PAL and still bad.
Dr yang's accent is the hardest barrier. while i don't like to hold that against him, if you can't understand what someone's saying, it can be hard to follow along. his lectures are good, and he gives a lot of examples. test were fair, and he does give part marks on the long answers. the course isn't hard, but a lot of individual effort is a must.
AVOID AVOID AVOID. Seriously, this course is hard enough as is, and with Dr Yang's language barrier, it is nearly impossible. Minimal examples, hard tests, very unclear about absolutely everything. Went from all A's to probably failing this course and I will say it is all because of him.
Dr. Yang makes this course 100x harder, Couldn't understand a single thing he was saying 90% of the time. Notes are near unreadable and straight out of the textbook. You will have to self teach this course if you take Dr. Yang. Seems like a kind person, but I recommend avoiding taking this class with him.
Run. With this teacher I also needed tutoring to even grasp what was happening. You will not understand him. Bad lab TA. The TA is extremely rude. Unorganized, just gibberish, would have dropped the course if it wasn't needed. So hard to focus in both lab and class because you won't know what's going on.
Like every other review here, Dr. Yang has an extremely thick accent. It makes the course more difficult. However, the examples in the notes are exactly what he put on the midterm/final or similar. The lab was extremely unhelpful and the TA was disorganized and only read off the slides with an equally heavy accent. However, both are very nice.
Yang cant speak fluent enough English to be teaching. This subject is difficult enough and the lack of good prof made this class miserable. There's a reason why several people took this course at cna to specifically avoid him. His notes wont help as they are a scribbled mess and barely eligible. Your best bet is outside sources to learn this course
very challenging to follow his lectures because of his accent, and the grading is based only on quizzes, a midterm, and a final, so there are no assignments to help improve your grade. I was able to get exactly 80 largely thanks to the tutor I hired, Kismat, whose practice questions were very very similar to what we could expect on the exams.
