Data Science Concepts

Not everyone wants to be a Data Scientist, but plenty of people want to strengthen their skills in the underlying competencies. It’s possible to learn key concepts in data science without going through a full-fledged program like those mentioned above. For a high-level overview of some key (and commonly confusing) terms, check out the GovEx Data Science Cheat Sheet. The list below includes the subject areas which are often taught in data science coursework.

The internet is rich with resources for learning data science. Plus, the community is an active one so join in and get involved! You can liberally use sites like Stack Overflow, R Bloggers, GitHub, and even Twitter to start learning from your peers, no matter your skill level as a data scientist.
