This was a lecture where I could learn about the data collection process, especially what web crawling is and what kinds of things can be done with it. Based on what I learned in this lecture, I think I can now seek out and learn more advanced data collection processes on my own!

This is a really good course! You only teach what's needed.

Just the right depth, not too much, not too little. They explained from the basics, but what I liked was that they didn't just end at the very basics and took us to a practical, usable level. They also provided direction intermittently, saying things like "This will be used for this later," which gave me an idea of how to move forward in areas like data analysis or machine learning. It was a practical and information-dense lecture, so the time spent wasn't wasted.
