Summary:

Data Science gets thrown around in the press like it's magic. Major retailers are predicting everything from when their customers are pregnant to when they want a new pair of Chuck Taylors. It's a brave new world where seemingly meaningless data can be transformed into valuable insight to drive smart business decisions. But how does one exactly do data science? Do you have to hire one of these priests of the dark arts, the ""data scientist,"" to extract this gold from your data? Nope. Data science is little more than using straight-forward steps to process raw data into actionable insight.
