She's a nice person but terribly boring, She doesn't teach she just does problems and has you watch. If you have the patience, go to class and just write down what she writes down and the tests are exactly the same as the examples that she posts on blackboard. Again, terribly boring, don't expect your interest to be enhanced but an A is achievable.

Took this class by accident (I had already taken a statistics class at my previous college) but I stuck with it because I thought it would be "fun", since I aced my last stats course.

Prof. Duncan is great; you can tell she really wants everyone to learn the material well. The labs are easy if you have a great lab TA like I did (take Laura Li!). Hardest part is remembering to do the online homework. If you do it well though you can get 100 and use that to study for the test. If you study the homework you'll ace the class.

Her lectures well summarize the readings from the textbook. The people saying her lectures are hard to understand likely did not read the textbook before the lectures.

I have mixed feelings about Prof. Duncan. All I've seen of her is in the form of lecture videos in which she does a great job at explaining the concepts. The in-person sessions involve a knowledgeable TA guiding the class through assignments posted on Canvas by Prof. Duncan, and you'll definitely have to study lots extra to keep up on the material.

Overall, STATS is a pretty hard concept to understand and Duncan doesn't do the best job at explaining the concepts and how to do problems. The lab grad student teachers try their best to explain the concept but if you want an A, I would suggest going to their tutoring hours.
