A quality control analyst is comparing the average defect rate across multiple production lines. Each production line has a calculated standard deviation for the defect rate. The analyst wants to show the average defect rate for each line and visually indicate the variability around that average. What should the analyst do?

Use the Analyze feature to explain the difference between the lines.

Add a reference line at the overall average defect rate.

Add error bars to the bar chart using the standard deviation values.

Create a scatter plot with defect rate on the x-axis and standard deviation on the y-axis.

A new analyst has been given a Power BI report with a complex semantic model that includes multiple tables and measures. The analyst wants to quickly understand what the model represents and get a natural-language summary of its key entities and relationships. What should the analyst do?

Create a clustering on the tables to see how they relate.

Add reference lines to each visual to infer the model's purpose.

Use the Analyze feature on each visual to understand the data.

Use Copilot in Power BI to ask for a summary of the semantic model.

In Power BI, where can you enable Anomaly Detection for a line chart?

In the Modeling tab under 'Security'

In the Fields pane by adding a measure to the 'Anomalies' well

In the Format pane under 'Shapes'
