Tutorial: Introduction to Tableau
Teacher: Tingying He
In this tutorial, you will use Tableau software to process and visualize data in an exploratory way (exploratory data analysis).
Before the tutorial
Install Tableau. You can request a free license as students here. Please note that it can take 1–2 days for Tableau Inc. to validate your student status, and thus to send you your license key. So start this process well ahead of the tutorial day.
Getting Started
The tutorial manual are available in this Google Docs. It includes all the content of this tutorial, along with step-by-step instructions.
Download the datasets: Data as CSV on Google
For French or other non-English computers, you may need to download the data in the TSV format for Tableau to correctly import the data.
Note: If you get problems in loading the CSV file (as described, this may happen for certain regional settings on your computer, such as French localization), open the dataset in your browser by clicking on the link, which opens it on Google, choose to open with Google Sheets, and then download the data in the TSV format. You could check that the data types when loading the data based on this.
Plan
We will explore the data, focusing primarily on Factor 1 (Constraints on Government Powers) and Factor 2 (Absence of Corruption), and get familiar with Tableau. We will:
- Load and prepare the data
- Drag and drop to take a first look
- Explore the data geographically
- Explore the relationship between two dimensions
- Add a filter to the view
- Create a dashboard
