I didn't know anything about real data, but it feels like you've laid out the groundwork for data analysisㅜㅜ It feels like you've laid out the outline of data analysis! Now I know how to do it even if I don't know much, and I'm so grateful that you've helped me understand the data analysis mindset itself!! It was even better that you briefly explained how to use other programs that can be used with GA! I really recommend this introductory course that's worth the money.
