How to calculate average of a column by multiple group as a new column?

[acaryasin01]

Hi guys,

If I have a data table like below,

How can I create a new column (below DESIRED COLUMN) which is calculated by Value grouped by Company's page no as an average. for each row.

How can get Average of Value for each page. returning value must be in every its row.

I wrote this dax but It returned average of Page no?!

But it returns same value for all rows.

Average of Same page's value = AVERAGEX(AEX , IF(EARLIER(AEX[pageno]) = AEX[pageno] , 1 , 0))

Compnay	Page No	Value	DESIRED COLUMN
A	2	30	35
A	2	40	35
B	2	30	40
B	2	40	40
B	3	50	40
C	1	10	15
C	1	20	15
C	3	20	15
C	3	10	15

Avg By Group = CALCULATE(AVERAGE(Sheet1[Value]),FILTER(Sheet1,Sheet1[Compnay] in {"A","B","C"}))

Thank you four you answer @mh2587 ,

I need these average value in all rows as a new column.

And also I have more than 70 company names, so I need more simple DAX.

Kind regards...
