    outlier_test = 
var rank_asc = RANKX(FILTER('Table',EARLIER('Table'[Month Restored])='Table'[Month Restored]),'Table'[Restored Hours],,ASC,Dense)
var rank_desc = RANKX(FILTER('Table',EARLIER('Table'[Month Restored])='Table'[Month Restored]),'Table'[Restored Hours],,DESC,Dense)
var count_row = COUNTROWS(FILTER('Table',EARLIER('Table'[Month Restored])='Table'[Month Restored]))*0.05
return IF(rank_asc<=count_row||rank_desc<=count_row,"Outlier","Normal")

     


    Best Regards,
    Liang
