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. 👍🏼

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.

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

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 😊😊
