Description
Before you can work with data you have to get some. This course will cover the basic ways that data can be obtained. The course will cover obtaining data from the web, from APIs, from databases and from colleagues in various formats. It will also cover the basics of data cleaning and how to make data “tidy”. Tidy data dramatically speed downstream data analysis tasks. The course will also cover the components of a complete data set including raw data, processing instructions, codebooks, and processed data. The course will cover the basics needed for collecting, cleaning, and sharing data. Please note: we are offering a Chinese version of this course starting Jan 5th, running in parallel with the English version. If you are interested, please select "Jan 5 2015 - Feb 2 2015 (中文版)" in the session drop-down list.
