It is interesting that major assignments in my PhD program were called signature assignments. I liked the signature assignments. I tried to make each one significant/noteworthy.
My first signature assignment was the paper on online reviews. I actually reused the knowledge in another signature assignment for the Statistics course that turned into a noteworthy paper too.
Statistics....
That was quite a course. I enjoyed it immensely although times were tough. I have a long history in statistics. My best grade at A Levels was in Statistics, specifically Pure Mathematics With Statistics. I also took lots of Statistics courses in the Economics program at UGy.
I remember that I rented the textbook for the course. Purchasing the book would have been better. Here is a photo from Instagram of the textbook I used for Statistics. I was returning the rental.

I also found a pic of the first page of the signature assignment for Statistics:
