    Hi LeoLi ,

     

    Here I suggest you to create a DimDate Table and a Level Table contains Days and "Sum", "Average" in it.

    DimDate = ADDCOLUMNS(CALENDARAUTO(),"YearMonth",YEAR([Date]) * 100 + MONTH([Date]),"MonthNum",MONTH([Date]),"Month",FORMAT([Date],"MMMM"),"Day",DAY([Date]),"DayKey",FORMAT(DAY([Date]),"00"))
    Level2 = 
UNION(DISTINCT(SELECTCOLUMNS(DimDate,"Value",FORMAT([Day],"00"))),{"Sum","Average"})

    Relationship:

    Measures:

    Count Error = CALCULATE(COUNT('Table'[Error Type]))
    Measure 2 = 
VAR _DAY = CALCULATE(COUNT('Table'[Error Type]),FILTER(DimDate,DimDate[DayKey] = MAX(Level2[Value])))
VAR _SUM = [Count Error]
VAR _AVERAGE = AVERAGEX(VALUES(DimDate[Day]),[Count Error])
RETURN
SWITCH(MAX(Level2[Value]),"SUM", _SUM,"Average", _AVERAGE,_DAY)

    Result is as below.

     

    Best Regards,

what do mean that column are error types? pls provide the output that based on the sample data you provide. That will be easier for us to understand the calculation logic. 

What's more , pls paste your sample data in your post,not the screenshot
