If you're a trained scientist, 'Data Science' sounds distinctly odd. What other kind of science is there? A friend likened it to going to a restaurant to do some 'Food Eating'.
In general, if the subject includes "science" in the name, it probably isn't actually science. Political, data, social, etc. No chemist needs to say they study "chemical science."
In Data Science, the word "Data" isn't meant to modify "Science" in the way that food "Food" modifies "Eating" in your friend's example. It's more like Political Science, where "Science" is used as a fancy way to say "the study and practice of".
All the more odd that Data Science is meant to be less scientific than Statistics (if the taxonomy I described in another post is correct).
