Hi, Anonymous 

Based on your description, i created data to reproduce your scenario. The pbix file is attached in the end.

Table:

Slicer:

You may create a measure like below.

Aggregation Measure = 
IF(
    HASONEVALUE(Slicer[Aggregations]),
    SWITCH(
          SELECTEDVALUE(Slicer[Aggregations]),
          "Sum",SUM('Table'[Value]),
          "Average",AVERAGE('Table'[Value]),
          "Max",MAX('Table'[Value]),
          "Min",MIN('Table'[Value])
    )
)

Result:
