@Anonymous  - All 3 measures involve a 2-step process.

1. Find the relevant rows.
2. Perform an Aggregation

Bottom 5 Average:

Bottom 5 Average = 
var _bottom5 = TOPN(5, 'YourTable', [YourColumn], ASC)
return AVERAGEX(_bottom5, [YourColumn])

 Top 5 Average:

Top 5 Average = 
var _top5 = TOPN(5, 'YourTable', [YourColumn], DESC)
return AVERAGEX(_top5, [YourColumn])

Top 5 Sum:

Top 5 Average = 
var _top5 = TOPN(5, 'YourTable', [YourColumn], DESC)
return SUMX(_top5, [YourColumn])
