Measure for group average

[Anonymous]

I have a measure for calculationg average of number of days since last input. 

I want to have another measure showing group average after filtering specific project to compare project with the group. I used function ALL to ignore the project filter but it is diving me average for all groups instead of the one i want. 

Group	average days	days group average
abc	10	10
def	20	20
ghi	30	30
	20	20

measure = calculate([average], ALL(project[id]))

when selecting one project from group abc, I need the other measure to be showing 10 as group average for abc but its showing average for all groups - 20

i wanted to try groupby but as my average is calculated measure i didnt think it would be useful. 

how to show second average for group ? when i select one project i want to see the average for the group the product is in.

Hi @Anonymous ,

Try this:

average = AVERAGE ( 'Table'[Days average] )

divisional average = 
AVERAGEX (
    'Table',
    CALCULATE (
        AVERAGE ( 'Table'[Days average] ),
        ALLEXCEPT ( 'Table', 'Table'[Group] )
    )
)

superb !! thank you so much for this ! 

would this work in a table as well ? I need a column in a table where for each row i want to see this group average (no not only when i select specific group).

I created this sample of data : 

Product	Group	Days average
a	abc	50
b	abc	60
c	abc	80
d	abc	100
e	abc	500
f	abc	100
h	abc	50
i	abc	60
j	def	70
k	def	100
l	def	100
m	def	120
n	def	140
o	def	150
p	def	160

I want to have a measure showing average for product(s) and another one showing average for division. (i will have 2 cards next to each other for comparison)

e.g. when i select project a it gives me : average 50, divisional average 125

@Anonymous  you can achieve this by following measures

Average by group = CALCULATE(AVERAGE('Table 2'[Days average]),ALL('Table 2'[Product]))

Average by Product = CALCULATE(AVERAGE('Table 2'[Days average]),ALL('Table 2'[Group]))

Hi @Anonymous ,

You can use ALLSELECTED. And it would be great if you could provide some sample data.
