Reviews of professor Jeonghee Kim

Rating: 1.0/5, difficulty: 4.0/5
You might notice that some of solutions he gives for his practice quizzes will have mistakes. In statistics N means population and n means sample. So to find the variance when it's N the denominatior is N, but if it's n then the denominator is n-1. He did n with denominator of n. Leaving that there will just confuse and mislead students.

As someone who has tutored statistics before I would say that prof. Kim butchers his explanations and makes things way harder than they need to be. Kim is all about the bare minimum, letting students make up the difference he creates in his lack of effort. The course is very disorganized and you will frequently be left in the dark. Don't take him.
