Comments on HW 05 coming up next week
Outliers: how do you avoid letting them skew your results?
No clear procedures; you make a decision and it will often affect your results!
some strategies:
Look at context (why would this be from a different population)?
Look for natural gaps in data
Avoid algorithms—if there could be a better reason.
Try with and without (does it change the results?)
Whatever you choose, justify your decisions!!!

March 04: Data Viz Interviews
NJ noticed something about our discussion from last time... (see images below.)
Data Viz Interviews
Remind your partner how to refer to you
Person closest to the door goes first
at ~20 minutes NJ will give the call to switch. You're welcome to switch sooner, or to ask follow-up questions. (This is your time!)
20 minutes for other partner, use the time to get responses and to ask follow-up questions.
Lat 10 minutes: NJ discusses Data Viz Presentations in more detail.
Format is about the same as DataFest
- 3 slides, 5 minutes
Rubric is given in the Data Viz Instructions (see step 9)
Things things previous years' students did well
- white space on slides
- pithy bullet points
- took on challenging graphs
I appreciate the honesty people had: I tried this; this worked & this didn't.
- thoughtful about factor order
- if alphabetical you need to justify it
- Well-rehearsed transitions, practiced.
Constructive Criticism/Suggestions from last year
- Make your bullet points meaningful, and other tips on the slides (slides)
- just because Tufte or Gelman or XYZ says it's important doesn't mean it's right for your story
- maybe you need to violate a data Viz principle? Then say why!
- You might want to simplify the data so your reader can see a story. (It depends.)
Think about color
- Think about the color scheme and what it suggests - (see colorbrewer palattes image)
- If the categories aren't ordered use a palette that doesn't suggest an order. (i.e., don't use red orange yellow green blue... or shades of the same hue)

- 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).

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.
