With Jeff Leek, Department of Biostatistics, Johns Hopkins
Data science is the process of formulating a quantitative question that can be answered with data, collecting and cleaning the data, analyzing the data and communicating the answer to the question to the relevant audience. I'll discuss the common (math, programming) and less common (question formulation, data pipelines) components of data science. I will use examples from our experience creating and maintaining more than 20 data science courses that have enrolled more than 4 million over the last 4 years to illustrate why the future of data science courses is based on plain text documents.
