What is data science?
Data science is a field of study that deals with using mathematics like statistics and large scale computing to build algorithms and models that explain information or predict outcomes and insights from structured, unstructured, and semi-structured.  Data scientists spend 80% of their time doing exploratory data analysis and about 20% of their building the model and hyper parameter tuning.
