Advanced Skill Test: Power BI Data Analyst Exam (PL 300)

In today’s data-driven world, the ability to analyze and interpret data is more valuable than ever. Power BI, Microsoft’s powerful business intelligence tool, empowers organizations and professionals to transform raw data into actionable insights. This comprehensive course is designed for beginners and intermediate users alike, guiding you through every step of Power BI, from data integration and modeling to building insightful dashboards and sharing findings with stakeholders. By the end of this course, you’ll be equipped to make data-informed decisions that drive organizational success.

Module 1: Getting Started with Power BI

We begin with an introduction to Power BI’s user interface and essential functionalities. You’ll learn how to navigate Power BI Desktop, the primary application used to create and develop your projects. The course walks you through the process of connecting to different data sources—such as Excel, SQL Server, and cloud-based databases—giving you flexibility with various data formats. By the end of this module, you’ll be familiar with how Power BI fits into a data analysis workflow and how to set up your workspace for efficient data exploration.

Module 2: Data Preparation and Transformation

Data in its raw form often needs significant cleaning before it’s ready for analysis. This module focuses on Power Query, Power BI’s powerful data transformation engine. You’ll learn essential skills for preparing data, including handling missing values, dealing with inconsistent formats, and merging multiple data sources into a single, coherent dataset. Additionally, we’ll cover advanced Power Query techniques, such as creating custom columns and filters, grouping data, and applying advanced transformations to make your data both consistent and analysis-ready.

Module 3: Data Modeling and DAX (Data Analysis Expressions)

Data modeling is a critical step in any analytics project, as it allows you to organize and structure data for efficient analysis. This module introduces you to Power BI’s data modeling tools and the basics of creating relationships between tables. You’ll learn the fundamentals of dimensional modeling, including star and snowflake schemas, which are commonly used for organizing data in business intelligence systems.

A key feature of Power BI is DAX (Data Analysis Expressions), a powerful formula language that enables you to create custom calculations, aggregations, and complex measures. In this module, we introduce you to DAX basics and walk you through practical exercises to help you create calculated columns, measures, and time-based calculations. By the end of this module, you’ll have a solid foundation in data modeling and will be able to design models that improve report performance and provide more insightful results.

Module 4: Data Visualization and Report Building

Once your data is prepared and modeled, it’s time to bring it to life through visualizations. This module dives into the art and science of data visualization, covering best practices for presenting data effectively. You’ll learn how to create and customize a wide range of visuals, including bar charts, line charts, maps, and matrices. We’ll also cover advanced visualization techniques, such as using custom visuals from the Power BI marketplace and designing dynamic visual interactions.

A key part of Power BI’s appeal is its interactivity, and this module demonstrates how to make your reports interactive and user-friendly by setting up slicers, filters, drill-through capabilities, and buttons. You’ll learn how to design report pages with multiple visuals that update dynamically based on user input, enabling end-users to explore data independently. By the end of this module, you’ll be able to create compelling reports that tell a story and provide a clear path from data to insight.

Module 5: Dashboarding and Data Storytelling

Dashboards provide a high-level view of essential metrics and KPIs (Key Performance Indicators) for quick, actionable insights. In this module, we focus on creating Power BI dashboards that convey key information at a glance. You’ll learn how to pin visuals from multiple reports to a single dashboard, organize and arrange visuals effectively, and design dashboards that highlight critical insights.

We also explore data storytelling techniques that help you present data in a way that resonates with your audience. You’ll learn how to structure your reports and dashboards to guide users through a narrative, making it easier for them to understand the data and act on insights. By the end of this module, you’ll be able to create dashboards that are not only visually appealing but also highly effective in communicating data stories.

Module 6: Data Security and Sharing

Ensuring data security and managing access are essential considerations when working with sensitive information. In this module, we discuss Power BI’s robust security features, including row-level security (RLS), which restricts access to specific data within reports. You’ll learn how to set up and manage permissions to control who can view, edit, and share your Power BI assets.

Once your reports and dashboards are ready, it’s time to share them with your team. We cover the various ways to publish and share Power BI content, including publishing to Power BI Service, sharing via Power BI apps, and embedding reports in other applications. We’ll also discuss options for exporting reports to PDF or PowerPoint for offline distribution.

Module 7: Power BI Service and Power BI Mobile

Power BI isn’t limited to the desktop application. In this module, we introduce you to the Power BI Service, Microsoft’s cloud-based platform for sharing and managing Power BI content. You’ll learn how to upload your reports to Power BI Service, set up scheduled data refreshes, and use the web-based interface to create simple reports and dashboards directly in the cloud.

Power BI Mobile allows you to access and interact with your reports on the go. We’ll guide you through setting up the mobile app, customizing reports for mobile view, and configuring notifications for real-time updates on critical metrics.

Module 8: Advanced Features and Customization

For users who want to go beyond standard Power BI functionalities, this module covers advanced features and customization options. You’ll learn how to create custom visuals, use Power BI’s AI-driven visualizations, and incorporate external data sources through APIs. We’ll also explore integration with other Microsoft tools, such as Excel, Azure, and SharePoint, to create a connected analytics environment.
