Who's Afraid of the Big (Bad) Data?

This presentation was part of a webinar series for the Youth Delegate Program, a one-year fellowship program for young actors of international development from all around the world. It served as an introduction to the know-hows of data science: where to find data, how to collect data on your own project or organization, and how (not) to use it to guide decisions and evaluate the impact of interventions.
