I would totally disagree with the term "Data Science." It maybe used loosely but it certainly is more than statistics and more akin to science. Any inter discipline study has these issues.

It is science since you are taking data to answer a question. If your not answering a question or using a scientific method it falls short.

Good example is all the medical data science that has been happening in the past decade or so. http://www.oreilly.com/data/free/how-data-science-is-transfo...
