Quiz 02 (based on these readings on Ethics in Data Science)
Rao & Andre (2011) summary of the MMR & Autism Vaccine story (~1.5 pages)
- I chose this because it describes an example of blatant ethical violations in data science that have affected society
Angwin et al (2016) investigation of the recidivism algorithm with lots of pictures. :)
- I chose this reading because it contrasts to the above; the ethical violations are not as blatant

Feedback from Reflective Report
Nervous about R? NJ is happy to help!
Regarding Group projects:
- Data Viz: you can work alone or choose a group.
- Qualitative Project: NJ chooses groups; collaborative work is done in class
- DataFest: you must work in a group, but you can choose
- Consulting project: you must work in a group, but you can choose. *occasional exceptions apply
DataFest conflicts:
- We can work out an alternative
- The kickoff on Friday is recorded; you can figure out with your group when to work on it.
- The closing ceremony on Sunday will have food & hybrid format, but regardless is optional.
- DataFest: What you put into it is what you get out. When determining a group, take into account if your goals are mutual.
