NJ comments on Reflective Report #3 (Qualitative)
Many students had never seen qualitative work before; appreciated an experience of what it's like
Sampling:
interesting that it's not necessarily a case when you want a representative sample; disproportionate is the goal so as to capture minority opinions.
practice with what to do when things don't go as planned
Remember:
In Vivo & Concept codes are just ONE WAY to analyze;
Phenomenology and Grounded Theory are just two of MANY approaches!
Consulting Project Interviews (pairings)
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.
Last ~10 minutes: Connect with your group about what you learned.

Some students in my data science class are interested in organizing a new Data Club on campus. The club is intended for students who are interested in anything related to data, including data science, analytics, visualization, AI/ML, research, and real-world applications of data across different disciplines.
Currently, the students are looking for members as well as students who may be interested in taking one of the five leadership positions in the club.
The club hopes to organize activities and events in the future, such as:
Inviting guest speakers from different fields to discuss real-world data problems
Organizing workshops and discussions on data analysis
Supporting interdisciplinary collaboration and small research projects
Creating opportunities for students to explore careers and applications related to data
I was wondering if you know any students who might be interested in participating, either as general members or as part of the leadership team, please feel free to recommend students for the leadership position.
Here is the interest form:
Please feel free to share this with students who may be interested (Ideally before end of this week so that we can set up the club before end of the semester)
Thanks!

I'm sorry I didn't think to warn students who might be triggered by the context.
Students liked having hybrid format for the closing ceremony.
Someone suggested hybrid for the kickoff too.
NJ wonders: did the online video for the closing celebration get better when we muted the classroom?

- choose your own group.
- consulting projects from the past
- letter to potential clients example
- Several students have datasets/projects they’re interested in, so ask around.
- If you can’t find a client, then find a dataset you’re interested and NJ will be your client.
- Think: Job interview, project you're interested in, something meaningful to you
- If you want to work with Human data, you need CITI training.
- The format will be different from last year, but....
- last year's proposal form draft , last year's presentation rubric draft, last year's written report rubric draft (These are SUBJECT TO CHANGE!)

Comments on Text Analysis Assignment (HW 00)
Text analysis is completely different from qualitative analysis.
I wanted to insert this assignment here so that you have an experience to compare to, and because there is a week or so before the qualitative project heats up in terms of work outside of class.

Comments on Final Consulting Project
- some consulting projects from the past
- Several students have datasets/projects they’re interested in, so ask around.
- If you can’t find a client, then find a dataset you’re interested and NJ will be your client.
- Think: Job interview, project you're interested in, something meaningful to you
- If you want to work with Human data, you need CITI training.

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
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)

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

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.
