Wow.....His lectures were completely disorganized. You were never sure which concepts or formulas you would need from them until you tried the homework and by then you'd forgotten them already, even if you did it right after class. The tests were relatively straightforward and were in large part based upon his review sheets so I ended up getting an A in the class. However I don't feel that I've truly learned very much at all about statistics. The lectures were just too fractured. It doesn't help that half of the stuff Dr. Li lectures about simply isn't in the book, and what is in there is horribly written. You're pretty much on your own. Pray you get a good TA.

Professor Li was enthusiastic about statistics and its importance in biomedical research, but he was one of the most disorganized professors I ever had. He'd come to class with his laptop but half the time it would not work. I was most fustrated by his teaching skills and order of homework and lectures because they often would not correspond well. It was very common to do a homework problem one week, turn it in, and then read about how it the next week instead of the previous. If it wasn't for the TA who went through homework problems in discussion and lab, I would have died in the class.
His exams and grading systems were fair though, and it was nice of him to give a practice exam beforehand.
