Microsoft Power BI Data Analyst (PL-300): Prepare the Data
Data quality determines insight quality—and most analysts waste time on messy datasets. This focused module teaches you the data preparation techniques that separate certified Power BI professionals from those stuck in spreadsheets. You’ll move from raw data to analysis-ready models in under 2.5 hours.
AIU.ac Verdict: Essential for anyone pursuing PL-300 certification or working with Power BI in production environments. The course is tightly scoped to preparation only, so you’ll need supplementary resources for visualisation and reporting—but that’s actually a strength if you’re building specialist depth.
What This Course Covers
You’ll work through data source connectivity, data profiling, and quality assessment—the unglamorous but critical foundation of any analytics project. The module covers transformation techniques including column operations, row filtering, and handling missing values, plus introduction to Power Query M language for repeatable workflows.
Practical labs walk you through real-world scenarios: connecting to multiple data sources, identifying and resolving data anomalies, and structuring tables for downstream analysis. By the end, you’ll understand why data preparation typically consumes 70% of an analyst’s time, and how to do it efficiently within Power BI’s native tools.
Who Is This Course For?
Ideal for:
- PL-300 certification candidates: Direct alignment with Microsoft’s exam blueprint; this module covers the ‘Prepare the Data’ domain comprehensively.
- Business analysts transitioning to Power BI: If you’re moving from Excel or Tableau, this teaches Power BI’s specific data preparation paradigm and best practices.
- Data engineers supporting analytics teams: Understanding Power BI’s preparation layer helps you design cleaner upstream pipelines and collaborate more effectively with analysts.
May not suit:
- Complete Power BI beginners: Assumes familiarity with basic BI concepts and Power BI’s interface; start with foundational courses first.
- Visualisation-focused learners: This is preparation only—no dashboards or reports. If you want end-to-end Power BI skills, pair this with reporting modules.
