What Is Data Science?
This is a book about doing data science with Python, which immediately
begs the question: what is data science? It’s a surprisingly hard definition to
nail down, especially given how ubiquitous the term has become. Vocal
critics have variously dismissed the term as a superfluous label (after all,
what science doesn’t involve data?) or a simple buzzword that only exists to
salt resumes and catch the eye of overzealous tech recruiters.
In my mind, these critiques miss something important. Data science, despite
its hype-laden veneer, is perhaps the best label we have for the cross-
disciplinary set of skills that are becoming increasingly important in many
applications across industry and academia. This cross-disciplinary piece is
key: in my mind, the best extisting definition of data science is illustrated
by Drew Conway’s Data Science Venn Diagram, first published on his blog
in September 2010:
