Average hours per day among staff (multiple lines per day per person)

[Anonymous]

I have searched the forum and googled but haven't been able to implement those findings to my scenario.

• I have one table: TimeEntry
• This table contains data for 4 years, approx 200 thousand lines.
• Some persons are working full work week, while others work fewer days.
  • Each person registers many lines each day.
  • This is why I need to somehow get the sum of hours per member.id as well as finding out how many days are behind those hours using date in timeEnd column.
• I need to create a measure that tells me the average hours per day in the workforce.

Hope someone can assist me.

member.id	timeEnd	hoursBilled
1	13.4.2022 08:30:00	0,5
2	13.4.2022 10:30:00	2,5
3	13.4.2022 12:30:00	4,5
1	13.4.2022 15:30:00	5,0
1	14.4.2022 12:45:00	4,0
3	14.4.2022 12:30:00	3,5
2	15.4.2022 09:00:00	0,5
2	15.4.2022 12:30:00	3,0
1	15.4.2022 12:30:00	4,5

Added for further explanation

If we use the little table I provided:

• Person1 works 4,67 hours a day on ave
• Person2 works 3 hours a day on ave
• Person3 works 4 hours a day on ave
• Total average a day in the workforce is therefore 3,89 hours

Hi @Anonymous ,

Please try this measure.

AVG = 
VAR _total = SUM('Table'[hoursBilled])
VAR _count = COUNTROWS(CALENDAR(MIN('Table'[timeEnd]),MAX('Table'[timeEnd])))
VAR _avg = DIVIDE(_total,_count)
RETURN
_avg

result.

Thank you for the reply Gao but this doesn't give the correct result.

If we use the little table I provided:

• Person1 works 4,67 hours a day on ave
• Person2 works 3 hours a day on ave
• Person3 works 4 hours a day on ave
• Total average a day in the workforce is therefore 3,89 hours

When I use your measure I don't get 3,89 as a result.

Hope you have time to look at this again.

Many thanks

Hi @Anonymous ,

First we need a date column, which you can create in PowerQuery.

then please create a new measure.

AVG = 
VAR _count_id =
    DISTINCTCOUNT ( 'Table'[member.id] )
VAR _avg_day_total =
    SUMX (
        SUMMARIZE (
            'Table',
            'Table'[member.id],
            "avg", DIVIDE ( SUM ( 'Table'[hoursBilled] ), DISTINCTCOUNT ( 'Table'[Date] ) )
        ),
        [avg]
    )
VAR _avg_day_person =
    DIVIDE ( _avg_day_total, _count_id )
RETURN
    _avg_day_person
