How can you use the "What If" analysis feature in Power BI?

The "What If" analysis feature in Power BI is a powerful tool that allows users to create parameters and simulate different scenarios within their data models. By creating a parameter, users can define a value range and then visualize how changes in that parameter affect the results in a report. For example, if you want to analyze how variations in sales price impact overall revenue, you can create a parameter for price adjustment. This gives you the ability to dynamically adjust the parameter in your visuals and see real-time results, allowing for informed decision-making.

This feature is particularly useful for financial forecasting, budget analysis, or any scenario where predicting outcomes based on different potential realities is beneficial.

In contrast, importing external data sources involves integrating other datasets into your model, which is not directly related to simulating scenarios. Grouping data into categories organizes data for better visualization but does not enable scenario analysis. Applying filters to report visuals allows for data segmentation but does not provide the interactive simulation capabilities that "What If" analysis does.
