One major topic in the Power BI Data Analyst exam concerns the use and implementation of AI visuals. Power BI integrates AI-driven visuals to provide interactive and insightful reports. These visuals not only enhance the clarity of data presentation but they also allow data analysts to identify patterns and trends that may go unnoticed with traditional static charts.
An example of an AI visual in Power BI is the Key Influencers visual. It allows data analysts to break down and visualize what factors drive a particular metric. To create a Key Influencers visual, you navigate to the Visualizations pane and select the ‘Key Influencers’ icon, then assign relevant fields to the required inputs. It employs machine learning to identify and display key factors that impact the assigned metric.
Another AI visual in Power BI is the Decomposition Tree. This visual lets the analyst break down a number into its contributing factors, allowing them to investigate root causes. The analyst can choose the next dimension to break the data down by, and Power BI will automatically highlight significant changes to help identify patterns.
