UnEarthing Data: Phytoplankton Part 1
In this video, Dr. Brad Hegyi discusses his thought process for analyzing data. He introduces ways to approach data to find interesting stories. He identifies five steps for a data exploration or “data dig”. He explains the first two steps in this video. The other steps are explained in UnEarthing Data: Phytoplankton Part 2. Note that the data he uses in this video are displayed on a map. You may not have thought about a map showing data, but these maps do just that.
