Key Concepts

Data should be publicly available. If you are working with data that is NOT publicly available or data that is part of a research project you MUST get consent from ALL parties involved to use the data. If you are working with your own research data, you must get consent from your research advisor before using the data in the workshop. If you have data as part of a collaboration withe others, you MUST get consent to use the data from ALL parties

Note: Handling and having access to the data, does not imply ownership of the data. If it is not publicly available, you MUST get consent to use it.

Data can be structured or unstructured.

1. Primary Data
2. Secondary Data
3. Tertiary Data

• What are the parameters?
• Dependent variable – variable being tested or examined
• Inependent variable – the variable that is changed or controlled to test the effects on the dependent variable
• In a table or spreadsheet format, generally, variables are represented in columns

• Audience: the demographic of people most likely to be interested in your topic/results/visualizations
• Assumptions: What aspect of the process are you treating as truth?

Self Assessment

Complete this assessment to demonstrate your current knowledge of the Acquire stage:

Review

Horizonal assessment of the acquire stage across the data visualization process mapped to Bloom’s Taxonomy of Hierarchical Learning

What you should know:

Bloom’s Taxonomy Hierarchy	You should know
Remember	What reputable data sources are and how to locate and access them.
Understand	The differences between primary, secondary, tertiary data sources and gray literature.
Apply	Demonstrate actions taken to acquire data.
Evaluate	Evaluating information sources is a multi-tiered process. You want to be able to answer the question: What does the information tell you about itself? You want to evaluate the credibility, reliability, and validity of your data sources. Validity is the question: “How do we know what we know.” It’s tricky. Look here for more about validity.
Analysis	How reliable is the data? How accurate is the data?
Create	Plan, generate, and produce data for a given project and cite your sources.

What you should be able to do:

Bloom’s Taxonomy Hierarchy	You should be able to do
Remember	Describe what happens in the acquire stage
Understand	Describe what stages are impacted by the acquire stage
Apply	Demonstrate actions taken to acquire data.
Evaluate	Explain how the data was acquired.
Analysis	Explain how the acquire stage impacts the visualization process.
Create	Plan, generate, and produce data for a given project and cite your sources.
