Mastering DAX and Data Visualisation in Power BI
Master DAX and Power BI to advance as an analyst
DAX is the analytical engine behind Microsoft Power BI, enabling you to create powerful calculations that transform data into actionable insights. On this three-week course, you’ll build the skills to write reliable DAX formulas and create professional, interactive reports that help organisations make informed business decisions.
You’ll begin by exploring DAX syntax, data types, and the difference between calculated columns and measures. As you develop your skills, you’ll apply aggregation, filter, logical, and text functions to solve real-world business challenges, from tracking revenue and profitability to measuring key performance indicators.
Develop advanced DAX and data analysis skills
Next, you’ll learn the advanced DAX techniques used by data analysts and Power BI developers. You’ll explore concepts such as filter context, row context, and the CALCULATE function, gaining the knowledge needed to build accurate, flexible business calculations.
You’ll also learn how to create time intelligence measures for year-on-year comparisons, use iterators to solve more complex analytical problems, and apply performance optimisation techniques to write efficient, production-ready DAX code.
Design interactive Power BI dashboards and reports
Great business intelligence is about more than accurate calculations. You’ll discover how to communicate insights through effective data visualisation by exploring the full Power BI visual library.
You’ll learn how to create engaging, interactive dashboards using bookmarks, tooltips, drill-through, field parameters, and conditional formatting. By the end of the course, you’ll be able to build polished, story-driven Power BI reports that help stakeholders explore data and make confident decisions.
