If you look at other no-code lectures, they often ask you to make code with chatGPT and use that code, but this lecture is really great because it doesn't use code at all. The lecture explains well how to give chatGPT good commands to get the analysis results you want, so even those who want to do data analysis but don't know any analysis tools can easily create the results they want. You can create a few things using the free version of chatGPT, but it's quickly limited. If you want to practice while listening to the lecture, I recommend subscribing to the paid version and listening together.
