Data Literacy

This guide was created to support the data literacy efforts of faculty, staff, and students at Tulane Libraries. If you have any suggestions for this guide, reach out to scholarlyengagement@tulane.edu

About This Guide

This library guide provides an overview of data literacy for those beginning teaching, learning, and/or research in this area. Visit the DATA LITERACY LIBRARY GUIDES page for library guides that describe each data literacy competency area.

If you are interested in offering data literacy instruction to your students, complete the following instruction request form: Library Instruction Request | TU Libraries (tulane.edu). Our librarians can offer instruction on basic data literacy topics such as determining appropriate collection method and data analysis. If you are a student looking to learn more about using data for your research or creative work, reach out to our team at scholarlyengagement@tulane.edu to schedule a consultation.

Data Literacy Defined

We hear the word “data” all of the time.

It is collected, analyzed, shared, hacked, bought and sold. But what exactly is data? Watch this video to learn more about data and its various forms. 


Data Literacy 

=

The desire and ability to constructively engage in society through and about data

 

According to Carlson et al. (2011), data literacy encompasses the following competency areas. You can use these competencies when planning data literacy instruction. Some areas are linked to related library guides. Visit these links for more in-depth descriptions of the competency area.

Potential Learning Outcomes for Data Literacy Instruction:

Critical and ethical data engagement must occur at each point in the data lifecycle.  The following data lifecycle models will help you think through the actions required to turn your data into insights for both short- and long-term use. Remember that each data use is iterative, so you may find yourself moving backward and forward through the data lifecycle. Visit the website of each organization to learn more about data literacy efforts occurring across the world
