Which of the following allows users to interactively filter data within Power BI?

• A. Measures
• B. Calculated columns
• C. Reports
• D. Slicers

Answer: (D)

Slicers are visual elements within Power BI that allow users to filter data interactively. They provide a way for users to segment and isolate the data they are interested in, right within the report. When a user selects a value in a slicer, the associated visuals connected to that slicer automatically update to reflect the selected data. This feature enhances the user experience by giving them control over what data they want to view, making it easy to perform data analysis and visualization tailored to specific needs. In contrast, measures and calculated columns are more focused on data calculations and transformations rather than user interaction. Measures are used for aggregating data, and calculated columns enrich data tables with new columns based on DAX formulas, neither of which provide a direct means for filtering data interactively. Reports, while they display the visualized data, do not inherently allow users to filter data without the inclusion of slicers or other filtering components. Thus, the use of slicers is essential for interactive filtering in Power BI reports.
