Working with Parameters, Filters, and Granularity

This masterclass teaches how to control a Tableau view with simple, reliable tools. It starts by explaining parameters as user inputs that drive calculations and switch KPIs or thresholds, then covers all key filter types and how they affect results. Learners see how granularity works, why adding or removing dimensions changes numbers, and how to choose the right level for a question. Along the way, short exercises reinforce the ideas with clean, repeatable patterns. By the end, dashboards respond smoothly to user choices while staying fast and consistent.
