About this rating

Raw average: 1.17/5 from 6 quality ratings. The adjusted rating blends this with the UW review average (3.66/5), weighted as 20 additional ratings. Smaller samples stay closer to that average. Each captured review is counted once in the prior; this does not correct who chooses to leave a review.

STAT 340
Quality 1/5Difficulty 5/5
Comparing her slides to the other professor's just showed me how much difficulty she added to the class because of her teaching style. The entire time, she would just be reading massive blocks of R code or reading formulas instead of saying anything useful or informative. She is a very nice woman, but I would definitely avoid her class.

Quality 1/5Difficulty 5/5
Lecture is just her reading off the slides, she provides no meaningful examples to deepen your understanding of the material, and the homework is absolutely nothing like the exams. She cannot convey the material clearly and in a manner that makes it easier to understand. SAVE YOUR GPA AND AVOID HER CLASSES. Don't make the same mistake I made.

Quality 1/5Difficulty 5/5
Lectures are worthless, many of them only took 60% of the allotted time. With tough materials such as present in STAT340, she should really be taking the full amount of time. Lectures were mostly her reading off slides. Little to no in-class examples done. Exams were written in a gotcha manner and did not match lecture difficulty well.

Quality 2/5Difficulty 3/5
Lectures were nothing special. She doesn't do live coding, and in that regard I liked Bi better (I had him for STAT240). Exams are fair and not too difficult. I attended almost all the lectures, but you definitely wouldn't have to (there are posted recordings and lecture notes).
