Course Info

In 2013, IBM reported that 90% of all data ever generated by humans was created in the past two years. Harnessing this data for actionable insight is key to securing competitive advantage in today’s business landscape. Unfortunately, current spreadsheet software is ill-equipped to handle this volume of data quickly and efficiently. This is where Data Visualization plays an important role.

Tableau is a drag-and-drop data visualization tool that enables users to arrive at insight through an intuitive graphical user interface. Learn about the fundamentals of producing visuals and visual analytics through several business case studies on this course.

Breaking down data silos is key to unlocking actionable insights.

  • Refresh concepts in set theory and learn about the different types of Data Joins
  • Establishing multiple simultaneous Data Connections
  • On the fly data connections with Data Blending

Learn the difference between buildings blocks of Tableau – dimensions, marks, measures and formatting. Creating commonly used charts such as bar, line & scatter charts. Tableau is a great tool for visualizing spatial data (geographic) and we will test out this capability by plotting choropleths with sample data.

  • Building for an intuitive interpretation

Stakeholders often have quite specific questions about our data that may require custom calculations.
What is the average for the last three months? How many customers had a late delivery? Table Calculations and Calculated Fields enable us to answer these questions directly on Tableau without having to manipulate data on Excel beforehand.

  • Table Calculations
  • Reference Lines
  • Calculated Fields

The whole is greater than the sum of its parts. Dashboards are a collection of visualizations that provide all key metrics at a glance. Tableau dashboards take this a step further by enabling interactivity – slice, dice and filter the data to drill down and discover the root cause behind business problems.

  • Assemble a dashboard from individual worksheets
  • Incorporate interactivity through dashboard actions
