Review

This module is taught by the Statistics Department, Prof Chan Yiu Man and Prof Yu Tao. I belonged to the lecture group of the latter.

There are 2 x 2hr lecture slots, but one of the lecture slots was used to watch the lecture recording, the other was simply a zoom lecture to consolidate the content learnt. For Prof Yu Tao, we requested for pop quiz every lecture which he gladly obliged.

There are 4 quizzes throughout the module totally 30% in total, then a final exam worth 70% (35 MCQ, or fill in the blanks, no partial marks, no backward navigation)

This module is a breeze for me since most of the content was taught during H2 Mathematics and Further Mathematics. However, there were new topics like F-distribution, Joint Probability Distributions etc. However, they were not much of an issue. If you own a graphical calculator, getting the answer is a matter of pushing buttons on it. I was very annoyed by the format of the Finals. I had to convince myself an answer is correct before moving on. There is no chance for any regret or dumb mistakes. Tutorials were a piece of cake. I attend the online Tutorials but paid zero attention to the tutor.
