Data scientists must have three key skills; data processing to collect and process the data needed for analysis scattered everywhere, analytical capabilities to create models and generate results for analysis and industry. Also, as data science is used in a unified sense of a variety of related disciplines, including computer science and statistics, it is difficult for an expert familiar with all these fields to exist. Therefore, in practice, data analysis is usually conducted by forming a team of various experts.

In an interview with a current data scientist, Jeon Jna, she said that she works as a data analyst, and it has been working three years since she came to Raynist after working at a large research laboratory. She added that they are developing the data analysis and machine learning services that they need for their services. The reason why she became a data scientist is her interest in data analysis and machine learning. It was interesting for her that the graduate school majored in data mining.

If you want to be a data scientist, you have to earn a bachelor's degree in IT, computer science, math, physics, or another related field. You can earn a related field. You can earn a master's degree in data or related fields, and you can also gain experience in the field you intend to work in such as in healthcare, physics, and business.
