This course begins by introducing the essentials of Tableau, helping learners install the software and navigate its interface with ease. Early lessons cover fundamental concepts such as dimensions, measures, discrete and continuous fields, and aggregation principles. These foundational skills empower learners to start exploring datasets, laying the groundwork for robust data visualization practices. Progressing further, the course dives into more advanced data manipulation techniques, including quick table calculations and level of detail (LOD) expressions. Learners gain proficiency in creating calculated fields and developing custom views to extract granular insights. With each module, the theoretical concepts are immediately reinforced through dashboard-building exercises, enhancing comprehension and application. The course culminates in a series of real-world projects that showcase the power of Tableau in various industries. Learners build interactive dashboards, including a sales analysis dashboard, a Netflix content dashboard, a financial complaints dashboard, and an investment portfolio tracker. These projects equip learners with the ability to present data-driven stories effectively, creating visual narratives that support critical business decisions.
