The hidden labor cost of inherited data

Although inherited data (a.k.a. secondary data) are cheaper to get than primary data, they're more expensive in terms of data scientist labor-hours. One reason is that you'll have to do lots of extra documentation and you'll also need to detective work to figure out the real story about how the inherited dataset was created. This video walks you through the extra documentation you'll be expected to produce.
