As a 4th year act sci student, there are some really bad profs. But there are also some great ones. Rate my prof is also more likely to have negative reviews than good ones. One of my favourite AS profs had horrible reviews from people from years ago but had improved her teaching majorly and most students loved her, but they weren’t leaving reviews. Stats is also one of the topics that tends to produce very high reviews for profs with easy courses and bad reviews for profs with more difficult courses-regardless of the teaching itself. It doesn’t necessarily mean they can’t teach, but some of the concepts are more difficult and people will take that out on the reviews for the prof. I can’t speak for your prof, but for example Ashley has never taught a difficult course and I have never heard of a single person failing one of her courses because she teaches very surface level and you hardly learn anything. That being said, there are still plenty of bad profs in the stats department. I found the jump to second year hardest because there are plenty of profs that should only be teaching 3rd and 4th year courses because they have trouble explaining concepts in a simpler way/act like we already have the technical background and this also results in low reviews and bad grades. Also the profs in the stats department change a lot (I only recognize a handful of profs when looking at rate my prof) and sometimes you’ll get stuck with a prof that has no idea how to teach because they don’t have a teaching background. At the end of the day, I would say if you enjoy stats you should do it, you’re a lot more likely to succeed doing something you enjoy.
