Reviews of professor Xiaofeng Xu

Rating: 5.0/5, difficulty: 3.0/5
Xu is knowledgeable about statistics, and he explains all concepts very well. The various tests and hypothesis testing approaches are taught in a well-connected manner; he explains the connections between those approaches and their dissimilarities clearly. Come to class and learn well, you will obtain power in stat.

You don't need to go to lecture unless there's a quiz, because his lectures are literally just screenshots of graphs from the textbook with zero context or explanation. He doesn't provide class expectations/study guides, so you basically just have to know the entire textbook. He has a thick accent and doesn't record lecture, so its hard to keep up.

Professor Xu is very kind and understanding right off the bat. Communicate with him any questions you have with the lecture, lab or exams. His accent/handwriting can be difficult to read sometimes, but the material is focused on R script and statistical analysis of relevant biological data. Good entry course and the TAs are phenomenal.

Xu is a nice instructor. all the test questions are in the slides or have been mentioned in the class. Some students do not come to the classroom but complain about the confusion in questions. anyway, attend class and pay attention to the questions in slides, assignments, and quizzes, you will earn a good grade. A fun and awesome course.

very nice person, try to come to classes for pop-up quizzes. the concepts are explained very clearly. Xu is a stat guy with a clear understanding of concepts and approaches. participate and work hard you will earn a decent score.

Dr. Xu is really passionate about his lecture and his research. Come to lecture if you want to get decent scores. His tests were fair although some confusions existed, yet it got better and better throughout the semester. His tests and quizzes pretty much from his slides and textbook; so come to class, read slides and textbook you will be OK.

His writing during lecture is awful. Can hardly understand him sometimes. He is a nice and caring teacher but i don't think he is good at teaching

Get the textbook and read. Lecture won't help. I think the following semester he's going to try to be a better teacher, but this semester (as his first time) was rough. The tests were written poorly and he didn't seem to understand why. But when we gave him feedback he would give us some points, so make sure to complain if he isn't being fair.

Xiaofeng is new to teaching and he's really smart and cares about the material but his lectures were really confusing and the slides were 90% graphs with no context and each lecture covered a TON of material over a few chapters at a time. Def buy the textbook and read/study that for exams, he asked rly specific things from the text. random quizzes.
