Prerequisites for Power BI Training

Before diving into hands-on Power BI training, it helps to cover a few basics:

• Access to Power BI Desktop - This free application lets you connect data, create models and design visualisations on your local machine before publishing to the Power BI service.
• Power BI Pro account - To share reports and collaborate, you'll need this premium plan. Consider costs and licensing needs.
• Sample data - Use the built-in retail demos or import your own data. Tableau Public offers free sample datasets.
• Resources - Microsoft's documentation, blog posts, and YouTube videos offer great self-guided learning.
• Cloud vs. Desktop - Understand that you design reports locally using Desktop then publish them to the cloud service.

With the fundamentals covered, you're ready to get hands-on to unlock the full potential of Microsoft’s industry-leading analytics platform.

Power BI's flexible architecture enables data connectivity and sharing between Desktop and the Cloud service.

Getting Started with Power BI Desktop

Power BI Desktop is a free Windows application you can install locally to create reports against data sources, shape data to your needs, and design interactive visualisations before publishing your work to the cloud.

To get started:

1. Download Power BI Desktop from Microsoft.
2. Open Power BI Desktop. Familiarise yourself with the Report, Data, Modelling and Visualisation panes.
3. Import data from a .csv file, Excel spreadsheet or other sources like a database server.
4. Use Query Editor to transform, enrich, reshape and clean your data as needed.
5. Model the relationships between tables in your data. Design your data structures.

Focus first on becoming proficient with Power BI Desktop for creating visualisations before moving on to publishing and sharing reports through the cloud service.

Cleaning and Transforming Source Data

Real-world data is often messy and needs preparation before analysis. In Power BI Desktop's Query Editor, you can:

• Remove errors and inconsistencies
• Reshape improperly structured data
• Enrich data by merging in supplemental tables or queries
• Add columns with custom calculations

By taking the time to transform and optimise your source data, you can create higher quality reports, dashboards and analytics.

Power BI Desktop provides data transformation capabilities to prepare raw data for analytics.

Visualising Data with Power BI

The true power of Power BI lies in its ability to generate meaningful visuals from your data automatically. Start simple, then expand to more advanced techniques.

Building Basic Charts and Graphs

Pick appropriate visual types based on your data structure and analysis needs:

• Bar and column charts to compare metric values across categories
• Line and area graphs to show trends over time
• Pie charts to illustrate part-to-whole relationships
• Scatter plots and bubble charts to analyse correlations

Modify visual properties like titles, labels, legends, colours, size, shape to make them clearer and more consumable.

Enhancing Analysis With Interactivity

Make your reports interactive so users can dive into the underlying data:

• Slicers: Filter visuals on specific values and ranges
• Highlighing: Choose data points to isolate and emphasize
• Drill-down: Navigate from summary views down to details
• Cross-filtering: Select data in one visual to filter others

Empower users to dive into key data points and uncover insights on their own.

Interactivity transforms static reports into engaging analytical experiences.

Advanced Visualisation Techniques

For more sophisticated analysis, take advantage of:

• Matrix visuals showing values across two dimensions
• Waterfall charts to illustrate sequential positive and negative changes
• Scatter chart trendlines to analyse correlations over time
• Combo charts overlaying line graphs on columns or stacked bars

With the right choice of visual matched to your analytical task, you can create informative reports that provide actionable business insights.

Designing Reports in Power BI

Once you've created effective visuals, you can begin combining them into attractive, easy-to-consume reports and dashboards.

• Arrange visuals thoughtfully across report pages
• Make key elements visually prominent through size and placement
• Format report backgrounds, add explanatory text boxes
• Establish hierarchies and relationships between report pages

By applying proper report design principles, you can guide users through a data narrative to reach impactful conclusions.

Creating Interactive Dashboards

Dashboards are an effective tool for distilling your key metrics and KPIs into a single pane of glass.

• Choose the most critical visuals to showcase on your dashboard
• Include drill-downs to underlying reports for deeper analysis
• Set automatic refresh intervals to keep dashboard data current

Well-designed dashboards empower users to visually monitor business performance at a glance.

Performing Analysis With DAX in Power BI

To move beyond basic reporting into advanced analysis, Power BI provides the DAX expression language.

DAX stands for Data Analysis Expressions. With DAX, you can create:

• Calculated columns - New data fields based on existing column values
• Measures - Aggregated numeric values based on calculations across tables
• Time intelligence functions - Trends, growth rates and forecasts over time

DAX formulas unlock the true analytical power of Power BI. Some examples:

Sales Growth Rate = 
DIVIDE(
    [Total Sales] - CALCULATE([Total Sales], SAMEPERIODLASTYEAR),
    CALCULATE([Total Sales], SAMEPERIODLASTYEAR)
)

Quarterly Revenue Forecast =
FORECAST(Sum(Sales[Revenue]), 4, QUARTER) 

By leveraging DAX alongside compelling visuals, you can conduct predictive and prescriptive analytics to transform business decision making.

Sharing and Collaboration with Power BI

Once you've designed effective reports and dashboards in Power BI Desktop, you can publish your content to the Power BI cloud service to share across your organisation.

Key features for collaboration:

• Publish reports to specific workspaces to control access
• Allow workspace members to edit and contribute to content
• Discuss findings collectively using commentary
• Subscribe users to push important updates to their inbox
• Integrate report visuals into Office documents or custom apps

With the right permissions, Power BI encourages teams to gain collective data insights that can elevate decision making.

Advanced Techniques to Take Your Skills Further

To become a true Power BI expert, continue expanding your knowledge:

• Use natural language queries with Q&A to get answers conversationally
• Connect to and analyse data within Analysis Services tabular models
• Stream real-time data from applications and devices to enable live dashboards
• Create custom visuals or incorporate R scripts for advanced analytics needs
• Automate reports and apply row-level security to restrict data access

By continually improving your Power BI skills, you can drive even greater business value through advanced analytics.
