What is a Data Scientist, exactly?

We hear all about the role of Data Scientist.

So I wonder what the average day is for a DS.

Do they typically meet with customers?

Do they have an assigned project manager who guides each phase of a project, setting timelines, expectations, etc.?

And how about QA, do they have a stop time where they send their product to a specific person or team to evaluate the accuracy of their findings?

These are some basic questions I'd like to know.

Also, who funds these positions, IT, Marketing, Research and Development?

And who exactly do they report too?

Recently there have been articles claiming the 'data scientist' is the sexiest position.

With all the publicity I still don't know what the position entails.

That's all I'm saying.
