Reviews of professor Corey Powell

Rating: 2.0/5, difficulty: 5.0/5
A great guy outside of class, but seriously struggles teaching material. Very unclear and talks as if we're at his level. Do not take this class unless it is absolutely necessary and you've taken AP Stats. Homework is graded on correctness and is very vague. Exams are incredibly hard and include handwriting code. Very helpful at office hours though

Dr. Powell was an understanding and helpful professor. However, he made concepts seem confusing by over-explaining them. The first midterm was ridiculously harder than the practice exams he gave. Assignments were unrelated to class content and graded on accuracy. He also expected us to memorize R code for exams.

This guy is a pretty bad lecturer, and sometimes I come out of lecture way more confused than when I come in. The lab is also horrible since it's very disconnected from class and convers completely different things. Just don't take him.

Boring and not a good lecturer

He is really nice and will always answer your question to the best of his ability. However, he makes simple things seem hard when he explains and talks really fast. Pretty non-engaging with his teaching in general. I think I learn better by reading his lecture slides and listening minimally.

Expectations on exams were very clear. STATS 280 was the most fair 4 credit college class.

Does not break down hard concepts well enough for students to understand as quickly as he expects. Impatient if lectures material is not grasped and makes it clear to students. Homework is long and graded on accuracy. Lots of coding using R studio.

Powell is a terrible teacher. Unless you have the ability to teach material to yourself, don't take a class with him. The textbook was way more useful than he ever was. His examples were more confusing than anything because of his terrible explanations. Unless you have perfect understanding of stats and R coding, you won't do well in this course.

Lectures are so confusing he makes the simple things too complex. People say he's disrespectful to students but I think he was fine. The lab is the least useful thing I've ever experienced my GSI just read code off the board and couldn't answer any of our questions. Take stats250 if you can.

He is not great at teaching but if you work hard, you can get a good grade because his class is basically curved. Homework, lab attendance, and writing assignments are easy ways to get points. If you have taken AP stats before, the class is very similar in content so it will be easier for you. The lab portion depends completely on the GSI.
