Power BI: Mastering DAX for Data Analysis

If you are already using Power BI but want to get more out of your reports, Mastering DAX and Data Analysis is for you. DAX (Data Analysis Expressions) is the formula language that powers Power BI, giving you the ability to create dynamic calculations, shape data effectively, and improve report performance. Whether you are struggling with complex measures, trying to fix unexpected results, or looking to speed up slow reports, learning DAX will help you take full control of your data.

In this fast-paced, hands-on, expert-led course, you will work with real-world scenarios to build DAX skills that make a measurable difference in how you create and manage Power BI reports. You will learn how to write accurate and efficient expressions, control how filters and row context impact your calculations, and apply advanced functions to solve common data challenges. You will also explore best practices for optimizing performance, setting up security roles, and using external tools to analyze and refine your formulas. By the end of the course, you will be able to create faster, smarter, and more insightful Power BI models that drive better decisions.

This course is designed for Power BI users who already have a solid understanding of basic report building and want to sharpen their skills with DAX driven data modeling and calculations. If you are a data analyst, business intelligence professional, or report developer, or if you work with Power BI in any role where accuracy and efficiency matter, this course will give you the tools and confidence to create more powerful and reliable reports. No prior DAX expertise is required. You just need a working knowledge of Power BI and a desire to improve your reporting skills.

In this expert-led, hands-on course, you will build the skills to confidently write and troubleshoot DAX expressions, improving the accuracy and efficiency of your Power BI reports.

By the end of this course, you will be able to:

• Write clear and effective DAX expressions that return the right results and are easy to maintain.
• Control how filters and row context affect your calculations so your reports always reflect the right data.
• Speed up slow reports by using best practices for DAX and optimizing your data model.
• Use CALCULATE and other key functions to create dynamic, flexible measures that respond to different filters and conditions.
• Set up Row-Level Security (RLS) to control access to data and ensure users only see what they should.
• Work with external tools like DAX Studio to analyze and fine-tune your expressions for better performance.
