Data Literacy
By far, the most important set of skills for data analysis is the abiltiy to easily get, manipulate, translate, summarize, and visualize raw data. In the end, it is always a very trivial thing to run the analysis, which is often just a few function calls. What takes the most time is taking the data that was given to you, figuring out why the person who gave you the data hates you and your free time, and how to reform it into something usable. That is what this course is about.
