Free online coursePower BI beginner to intermediate

Course Description

Build confidence turning messy spreadsheets into insights that people can actually act on. This free online course takes you from Power BI beginner to a solid intermediate level by guiding you through the real workflow used in reporting and business intelligence: getting data in, shaping it, modeling it correctly, and presenting results with clear, compelling visuals.

You’ll start by understanding what Power BI is and how it fits into a modern data analytics toolkit. From there, you’ll work inside Power BI Desktop and learn settings that make your environment smoother and more reliable. A strong focus is placed on Power Query because clean data is the foundation of every good report. You’ll practice using Transform Data to open the Power Query Editor, fix common issues, and prepare datasets so refreshes work consistently instead of breaking at the last moment.

As you progress, you’ll see how separate files and tables come together in a useful model. You’ll learn why merge queries matter when you need to combine information across sources, and you’ll understand the kind of problems that cause visuals to disappear or show incomplete results. Instead of memorizing clicks, you’ll build a mental model for diagnosing what went wrong and how to correct it efficiently.

The course also emphasizes modeling choices that unlock better analysis. You’ll explore why adding a dedicated dates table is essential for time-based reporting and for making filters and trends behave the way decision-makers expect. You’ll use calculated columns with intention, including formatting values for readability, and you’ll understand when calculated columns help your model support more meaningful reporting.

By the end, you’ll be able to prepare data, connect tables thoughtfully, and produce dashboards that communicate insights quickly—skills that translate directly into day-to-day tasks in data science and business intelligence roles.
