how to become professional data scientist
A data scientist is anyone who analys and interprets data to strengthen or align with a company's overall goals.
Essential things to do for becoming a data scientist are
- work on your mathematical skills
- programmatic skills
- learn SQL
- study machine learning (in any language, most commonly used language in ML nowadays is python)
- get some work experience as a data analyst
- sharpen your skills with an online course or bootcamp.
For relevant master's degree, you can go for Mathematics, Astrophysics, statistics or any other related field. But Data Science is a very different domain, no single degree can cover all the disciplines of the subject.
