In Power BI, which of the following is used to filter data visually?

Slicers are a visual filter tool in Power BI that allows users to segment data interactively. They provide a user-friendly way to slice data by creating an on-screen filter, enabling viewers to adjust the data displayed in reports dynamically. Users can select values from a visual list, and corresponding visuals on the report page will update to reflect the filtered data based on their selections.

This differs from calculated columns, which are used to create new data columns based on existing data within the dataset. While they might influence reporting indirectly by providing more data to work with, they do not interactively filter data for viewing purposes.

Data models refer to the structure and relationships within the data and are essential for data organization. However, data models do not provide a visual interface for filtering data and instead focus on how data elements relate to each other.

Measures are calculations made on data, typically using DAX expressions, to derive metrics and insights such as sums or averages. Like calculated columns, measures provide valuable analytical information but do not offer a way to filter data visually.

Thus, the functionality of slicers is uniquely suited for visual filtering in Power BI, making them the correct choice in this context.
