I'm an aspiring data analyst preparing for job hunting. [Reason for Taking the Course] While I had opportunities to study and practice other methodologies like funnel and retention analysis, I never had a chance to experience A/B testing even indirectly. So I chose it as my Halloween Challenge course and completed it in just one day. [What I Liked] As 거친코딩 mentioned, learning about the overall nature and cycle of A/B testing was very helpful. The P-Value part is still difficult, but I think I can gradually fill in those gaps. Thanks to the course, I now clearly understand why job requirements ask for Python or statistics knowledge and at which points they're needed. [Regarding Prerequisites] I only knew very basic knowledge like sample means and normalization, and except for a few parts, I understood it well. I think if I review the statistics part again, I'll be able to digest 100% of it. Thank you for creating such a great course! I always lacked confidence in A/B testing, but through this course, I was able to draw a foundation, which was very helpful. 👍🏼

You explain things really well from the student's perspective with great attention to detail.

It was disappointing that the content seemed to follow a simple book table of contents rather than focusing on practical, hands-on material. I feel like there could have been much more content that allows for deeper exploration through follow-up questions on specific concepts, but it only covered basic concepts before moving on, making it difficult to learn in-depth material.

Thank you for the great lecture!

You explained the key points so concisely and clearly that it's easy to understand!!

Your explanations are so good! I originally listened to a lecture by Nadocoding once, but I think it's better because you go into each topic much deeper than they did. Nadocoding only taught what was absolutely necessary for machine learning, so I thought pandas was only used for machine learning;; Anyway, that's why Nadocoding's lecture was harder for me to understand... But now, Geochincoding, you go into such minute detail, which is great! Please continue to create many great lectures in the future!

The explanation is very clear and the teaching materials are also helpful, making it very easy to understand!! It's the best for getting started with AB testing 😊😊

I learned a lot about Pandas! Thank you for the great lecture~~!

I was amazed by the amazing lecture skills and again by the fluent English skills. It was a wonderful lecture! Thank you!

Thank you for the great lecture!
