Mastering DAX for Microsoft Power BI

3-Day Instructor-led

Learn the full range of DAX functions in Power BI.

DAX is the native language behind Microsoft PowerBI and other Microsoft data tools. It’s designed as a flexible, powerful syntax for working with various data types and crafting functions to manipulate and analyze data.

Even for beginners, PowerBI out of the box offers incredible analysis capability. However, for those who are comfortable with basic features and are ready to truly unlock PowerBI’s potential, DAX is the key. Learning to use DAX within PowerBI gives you the power to perform incredibly fine-grained analysis and data manipulation.

In this class, you will get hands-on experience with DAX and learn it’s full range of functions. Led by an expert, you’ll get practice applying DAX skills to real-world datasets and real-world analysis problems. You’ll leave class ready to extend your role well beyond that of most PowerBI users – applying skills to manipulate, analyze, and communicate about data precisely and powerfully.
