Data Viz
Data viz is nothing new.
At the simplest level, we frequently interact with pie charts, graphs, and maps.
Define data visualization

Review history of applications and theory
Visualizing your Data
Choose the Tool
Give focus to your data
too cluttered
too much information
too much text
Pitfalls
Start with the end in mind. What story do you want to tell? Why do you want to tell it? What are you trying to answer?

Validate, justify, contextualize focus. Give focus and purpose to the data, give it structure.

Identify your audience. What message do you want them to walk away with?

Stay true
to the story
to the principles of design
to the data

Show, don’t tell

Don’t overuse/abuse colors/fonts
gestalt principles
Less is more/clean simple design

Consider cultural implications. What icons are familiar? What colors are meaningful?

Consider visual impairments such as colorblindness
theory,
application,
a pictorial timeline of sorts
Data Visualization
tells a story
(trends, correlations, relationships, outliers, context, narrative, processes)

The story of 2.5 million Michigan voters from last week.
The NYT Election Maps
Big Data
the amounts of raw data, both qualitative and quantitative, available to us

Technology

cloud-based tools, geospatial tools, infographics, text mining tools, analysis tools

Emerging Pedagogies
metaliteracies on visual and graphic texts in addition to the established disciplines of graphic design

Enhanced Research
digital projects, interactive web-based publications, wider dissemination
What is new
Overview of technical process

Brief review of tools and best practices

With Qualitative data, text sources may or may not be digitally born
Preparing Data for Analysis
1.
Digitize material
if not digitally born

Digitize, transfer



2.Clean data, make it easier to read.

Reduce noise (clean up typos, etc..) discrepancies, removing unnecessary information to make it easier to read, get better results.

Remove stop words (lemmatizing) or tell the computer to ignore certain variations (stemming).

Visualized Article
: Just like it sounds, taking a text heavy document and visualizing it.

Useful Bait
: This kind of infographic is more of a pragmatic tool. A good example is an infographic that explains measurements.

Flowchart
: Gives a choose your own path approach to a story

Timeline
: Data is visualized chronologically

Versus:
Presents 2 opposing ideas

Number Crunching
: Just the numbers, ma'am

Photo / Data Visual:
Use images from the real world to emphasize a story, focus on the artistic qualities of the story.

Data visualization

is automatic and raw data, as you would see in a graph.

There is a magic in graphs. The profile of a curve reveals in a flash a whole situation — the life history of an epidemic, a panic, or an era of prosperity. The curve informs the mind, awakens the imagination, convinces. -1939

T.S. Eliot's
The Wasteland

XML editor like Oxygen or XML Notepad.

Text editor software

photo editing software?
1. Identify Text TS Eliot's The Wasteland

2. Digitize text. I am using a version from Project Gutenberg: http://www.gutenberg.org/files/1321/1321-8.txt

3. Clean, mark up text with xml editor. or go through one-stop shopping tool like Voyant.

4. Analyze with your lens in mind.

5. Visualize

Final Platitudes
Qualitative data has a place in academic research.
Visualizing that data can be a powerful tool to communicate, influence.
Stay true to the interpretation, focus, or lens that you are using to present your qualitative data.
Know that variables can and will change during qualitative data collection and analysis. It is messy. That is normal.
We are fortunate to have a suite of tools available to us. It is not instant but with a little work, some beautiful documents can be produced.

(There is a funny story about this title.)
Data viz allows for an immediate recognition and connection to the data.
During a data visualization project,
Step 1
Step 2
bells and whistles
privacy issues
limited free access
no storage
stability, reliability, future access in question, may disappear
Best program may be a matter of preference
Let's Walk through a project.
1.Get data
2.Digitize data
3.Analyze date (with two software tools)
4.Choose an infographic analogy
Text from student answers defining plagiarism
fear not, no identifying information forthcoming
student work from Spring semester 2015
student work from fall semester 2015
born digital from an online survey
Prep Data
Though born digital, still need to clean it up.
In reading the various plagiarism policies in this chapter, how would you write a plagiarism policy for younger scholars? For more experienced scholars? How does plagiarism change as a scholar grows over time and with experience? How does accountability change?
1. Grab text (literally copy it)
2. Paste it in a text editor (small scale project)
3. Clean up any noise, unnecessary text, typos, etc...
My question to the graduate students was:
What do I want to know?
The variations in language from one semester to the next? On time? Accountability? Adjectives used?

Positive language? Negative language when describing plagiarism?

Do I need more research?

Do I want to add demographics back into the data?

Do I want to know what their undergraduate major was?
I've graded the homework so I already know what to expect at a basic level.
But with larger batches of data, you can let the patterns and relationships emerge by themselves.
