Your dashboard is beautiful, but is it smart? Welcome back to Chapter 6 of our Power BI course! I’m Nivea, and in this episode, we’re diving into the heart of Power BI: DAX (Data Analysis Expressions).

We’ve covered the basics—data transformation, building reports, and simple measures. Now, it’s time to master DAX to create dynamic, high-impact visualizations that drive real business insights!

🚀 What You’ll Master in This Chapter:

This video is your deep dive into powerful calculations, variables, and time intelligence. Get ready to transform your raw data into actionable metrics!

DAX Fundamentals & Best Practices
Measures vs. Calculated Columns: Learn the critical difference—why measures are “freshly cooked” and always preferred for performance and dynamism.

Measure Conventions: Understand the right way to organize and write your DAX to keep your model clean and efficient.

The Power of CALCULATE: Discover the single most important DAX function. See exactly how CALCULATE modifies the filter context to deliver precise, scenario-based results (like sales for a specific city AND fuel type).

Time Intelligence & Business Growth
We’ll build essential Time Intelligence Measures to gauge performance over time:

💰 YTD, QTD, & MTD: Calculate Year-to-Date, Quarter-to-Date, and Month-to-Date totals.

📈 Growth Analysis: Derive the all-important Month-on-Month (MoM), Quarter-on-Quarter (QoQ), and Year-on-Year (YoY) growth percentages.

Advanced Techniques: Variables (VAR)
Why Use Variables? Learn how VAR improves the readability, reusability, and performance of complex DAX formulas.

Practical Application: We’ll use variables to solve a real-world problem: calculating the latest fuel rate based on location, ensuring our measure only respects the location filter using the powerful ALL EXCEPT modifier.

Don’t just build a dashboard—build a data model that thinks! If you’ve been following our course, I highly recommend watching the previous chapters to stay on track.
