How to do it...

To implement this recipe, perform the following steps:

1. Create the following measure:

Mode = 
    VAR __Table = 
        SUMMARIZE(
            'R08_Table1',
            'R08_Table1'[Method],
            "__Count", COUNT('R08_Table1'[Method])
        )
    VAR __Table2 = 
        FILTER(__Table , [__Count] = MAXX( __Table , [__Count] ) )
    VAR __Mode = 
        IF(
            COUNTROWS( __Table2 ) = 1,
            MAXX( __Table2 , [Method] ),
            CONCATENATEX( __Table2 , [Method] , "," )
        )
RETURN 
    __Mode

2. Create a Card visualization and place the Mode measure in the Fields area for the Card visualization.
