I felt like I lacked the basics for studying statistics, so I listened to the instructor's previous lectures! I studied linear algebra and thought I knew a little bit about it, but as I listened to the lectures, I realized that I didn't know much. The best thing about listening to the lectures was that I felt like the concepts that were separate were organically connected to some extent. I just finished the lecture today, and I'm going to review it again and study statistics based on what I reviewed, and I'm going to build a solid foundation in statistics. Thank you for the great lecture :)
