This class was straight up legendary UNTIL assignment 3 and the final exam. Most people had high 80s to high 90s before these 2 assessments. Idk what she will do next term, I hypothesize that she will try to make the difficulty more even so you guys taking it in the future should still definitely study for the first midterm, but for us, it was basically a free 100, but assignment 3 and the final dropped a BUNCH of people to low 80s or high 70s.
However, people are lying, we did in fact get the exam curved, it went from 30 percent to 20 percent, and the grades I believed were adjusted although im not too sure. The professor was a sweetheart, and she was not responsible for the jump in…Dec 2025 · liked it · 1 found this helpfulOn UW FlowRemove this
Taken in F25. Up until the midterm, the material was straightforward, grading was fair, and expectations were clear. Doing well in the course felt achievable, and many students were performing strongly. I personally had a 97 going into the final.
After the midterm, everything changed. The third assignment was graded extremely harshly compared to earlier work, with little consistency or clear justification. The biggest issue, however, was the final exam. It was genuinely the worst final exam I have ever written. The difficulty level was completely unreasonable, and it did not reflect the course content at all. The majority of the class failed the exam, with most students scoring between 30…Dec 2025 · didn’t like it · 1 found this helpfulOn UW FlowRemove this
stats at 8:30am is not awesome, but being in-person is super rewarding! Ashok is a really fun professor and makes the exam questions really straight-forward...if you absolutely know your stuff! His practice exams and worksheets are really useful for studying, make sure to look for patterns in the lectures, worksheets and practice exams for what to study and TALK TO YOUR TA'S they are awesome!

$150...for a calculator. We are health science students not in the math department.

This course will make you think you have died for the first month, but once you get your sea legs you will eat it up (as much as one can eat up stats). Everything is taught using a TI84+ (or equivalent) graphing calculator which are expensive af. When I took the course, we were told this on the first day and just expected to go seek one out, they are not easy to find, and pay like $150 for it. The prof is a math prof, yes he is in SPHS, but spiritually (and educationally), he's a math prof. This means he will not try to be your bestie, but he will teach you stats effectively. The graded components were 3 midterms, weekly tutorial assignments, and 6 problem sets. The tutorials are VERY…
