DATA SOURCING // FOUNDATIONS OF DATA SCIENCE, PART 2

Data science can’t happen without data. That means the first task in any project is source – that is, to get – the raw materials that you will need. This short course discusses some of the more familiar methods of gathering data and some of the less familiar that are specific to data science. Data Sourcing is the second of five courses designed to outline the principles and practices of applied data science.
