Bijan’s Answer

Hi Taeseong,

Data Science is very much an art of story telling. You need to be proficient in the technical side of Data Science ie getting familiar with R & Python, leveraging modules like pandas, matplotlib, etc. but also you need to tell the story of the data to non-technical audience and c level suite. Like others have said, don't underestimate the math side of things which are critical. I would recommend leveraging any free resources to develop your skills. Elon Musk has said that you can learn anything you want for free. There is a significant amount of information on the internet.

Vijayanand’s Answer

All the answers by Heine & Mingze are relevant. I would also add that if you are in school, focusing on Math - Probability and Statistics and Linear Algebra, Vector Algebra is critical for being a good data scientist. Ofcourse, the programs on coursera.org are then building on top of that.

Good luck. this is a hot field, so the industry has a lot of demand for good data scientists.
