- How to refer to you
- What is your biggest buyer's remorse purchase or your biggest time-spent remorse show or movie?
gapminder video classic data viz example: https://www.youtube.com/watch?v=jbkSRLYSojo
Next step on Data Viz: Everyone conducts at least 2 interviews (completed & submitted individually)
- One interview is with the member of this class assigned to you
- One is with an additional "audience" member of your choice (you may conduct several of these if you wish)
- If you want to present multiple candidate graphs, randomly assign which order they are presented, and flip it for the other interview. (Don't always present the same graph first).
- A big part of your project is what you learned/adjusted based on your interviews
Exchange contact info with the group member sitting beside you; this is your assigned interviewee from this class
Wednesday of next week: bring your viz so you can get feedback from your interviewee!

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.
