The Frequency Matrix: A Tableau Technique You're Missing

No comments

What if the data you already have could reveal something you've never seen before? It can, and it starts with a technique most Tableau analysts have never tried: the frequency matrix. In this full keynote from Appalachian State University's Analytics Day, Andy Kriebel (Tableau Hall of Fame Visionary and founder of Next Level Tableau) builds a frequency matrix from scratch, then shows the same underlying data six different ways: Sankey diagrams, tree diagrams, network diagrams, geographic flow maps, box plots, and slope graphs. You'll walk away with a technique you can take straight back to your own data, whether you're working with enrollment numbers, customer flow, product usage, or anything else where you need to compare two categories at once. What's covered: - What a frequency matrix is and how to read one - Building a frequency matrix step by step in Tableau - Using calculated fields to highlight the most common and highest-performing combinations - Visualizing the same relationship with Sankey diagrams, tree diagrams, and network diagrams - Mapping geographic flow with Make Point and Make Line - Guiding principles for building dashboards stakeholders actually use - Live Q&A on accessibility, color palettes, and chart governance Want more?
