I am Gemma, a data analyst who started in mathematics, moved into a developer career, and eventually settled into my current role after studying statistics. In data analysis, the most important thing is identifying novel insights and trends within the overflowing sea of big data. That’s easier said than done, right? However, if you can utilize the right analysis tools and methods, anyone is more than capable of discovering valuable gems. I would like to share these methodologies with all of you.

I think the best part is that it broadens your perspective by teaching you rich and diverse approaches to each problem type. Usually, other lectures assume everyone already knows this and just skip over it or skip the explanation, so it's hard to understand, but this lecture explains it step by step in detail without skipping any part of the solution process, so you can understand it really well without missing anything. I think the lecturer is really meticulous by nature.
