The Value of Data Science Education

Much of the value of data science lies in the use of its theory and methods to provide concrete and actionable solutions to complex substantive problems. To do this well, however, takes much more than merely learning theory and methods in classrooms or from books. It require ‘data acumen,’ a central emphasis of the US National Academies’ report on undergraduate data science education. Gaining data acumen requires one to be exposed to the complexity and scope of data science process in actual practical settings, just as there is no other way of learning to swim than actually diving into the water, and trying to stay afloat while moving.

“Here's why you only have a 0.2% chance of getting hired at Google”

Google gets around 3 million applications a year now, according to HR head Laszlo Bock, and hires 7,000. That means only one in 428 applicants end up with a job, making it far more selective than institutions like Harvard, Yale, and Stanford.
