calculate variance of measure

[yishenhui]

Hi,

I want to calculate variance of a measure. The measure is 

%ofcapacitybasedondaysworked =

sumx(SUMMARIZE(DataQuery,DataQuery[AnalytName],"Documented",SUM(DataQuery[Time Spent Day (H)]))

,[Documented])   /sumx(SUMMARIZE(DataQuery,DataQuery[AnalytName],"DayXWorked",DISTINCTCOUNT('DataQuery'[Day])*sum('ContactsCapacityQuery'[Hours]))

,[DayXWorked])

It was re-written as I thought it could be grouped by analytName. However, when I use it in the measure of variance, it seems doesn't work. The measure of variance is 

Variance of Documented =

var temptable=ADDCOLUMNS('DataQuery',"analytname1",DataQuery[AnalytName],
"%cap",sumx(SUMMARIZE(DataQuery,DataQuery[AnalytName],"Documented",SUM(DataQuery[Time Spent Day (H)]))

,Documented])

 /sumx(SUMMARIZE(DataQuery,DataQuery[AnalytName],"DayXWorked",DISTINCTCOUNT('DataQuery'[Day])*sum('ContactsCapacityQuery'[Hours]))

,[DayXWorked]))

   return

Varx.p(temptable,[%cap])

The results of variance are all zero. It supposes have some non-zero numbers (like the seconds screenshots from exported data and variance from columns)

What is wrong of my DAX?

Thanks
