In his talk earlier this week, Hayo cited 8 types of data from Purdam and Elliot (2015 - see https://drive.google.com/file/d/0Bxa1ZO ... dKazA/view). These are:
1. Orthodox intentional data (e.g. surveys, interviews)
2. Participative intentional (e.g. crowdsourcing)
3. Consequential data (e.g. admin records)
4. Self-published (e.g. blogs)
5. Social media (e.g. Twitter)
6. Data traces (e.g. search histories)
7. Found data (e.g. observations)
8. Synthetic (e.g. simulations)
Numbers 2 and 3 strike me as particularly interesting, since they are rarely considered but could be done (I also think number 6 is interesting in the same way, but doubt that data could be collected).
Can anyone come up with interesting research projects that would use either crowdsourcing data or consequential data?
