I don't usually leave course reviews. I hope there is no misunderstanding because everyone's feelings may be different. I will share some of my thoughts so that other students can refer to them. - This course focuses on data analysis. It is different from other courses that are woven together to make them look rich. - The basic lecture content that is helpful for beginners is good. In particular, preprocessing must be done well for analysis to be done well, and the preprocessing part is explained in various ways to create the same result. So, you will naturally become familiar with the detailed options of the functions used in preprocessing. - Lastly, the course answers questions much faster than other courses. There was even a time when the course answered while revising because I thought I had insufficient questions. From the perspective of a learner, even if you learn the same thing, each person has different questions they want to ask, but the course answers each question really well. I recommend this course to those who want to learn only data analysis without being impatient and trying to learn various IT techniques in a taste-based way.
