What is a slicer in Power BI?
A slicer is a visual filter that lets users select values to filter data on a report page easily.
What are the three common slicer types in Power BI?
The three common slicer types are List, Dropdown, and Between (for numeric or date ranges).
How does a 'Between' slicer work?
A 'Between' slicer lets users select a range between two values, such as dates or numbers, to filter data within that range.
When should you use a Dropdown slicer instead of a List slicer?
Use a Dropdown slicer when you have many values to save space and keep the report clean, as it shows a compact list users can expand.
What is a best practice for accessibility when using slicers?
Ensure slicers have clear labels, keyboard navigation support, and sufficient color contrast for all users.
Which slicer type allows selecting a range between two values?
The 'Between' slicer lets users pick a range between two values, such as dates or numbers.
What is the main advantage of using a Dropdown slicer?
Dropdown slicers save space by hiding the list until clicked, keeping the report clean.
Which slicer type is best for filtering categorical data with few values?
List slicers show all values and work well for categorical data with few options.
How can you improve accessibility for slicers?
Clear labels and keyboard navigation help all users interact with slicers effectively.
What happens when you select a value in a slicer?
Selecting a slicer value filters the report data to show only matching results.
