Daily average in calculated column

[Anonymous]

Hi Community,

I'm trying to find a way to calculate a daily average of a hourly prices of a certain market on historic series of 5 years. I need it in a column once I need to take that figures for a further join table.

The data is in this "Sample Table":

Date	Price
2021-05-06	5
2021-05-06	3
2021-05-06	1
2021-05-06	1
2021-05-06	2
2021-05-05	2
2021-05-05	3
2021-05-05	1
2021-05-05	4
2021-05-05	5

And the desired output is this format:

Date	Price	Daily avg
2021-05-06	5	2.4
2021-05-06	3	2.4
2021-05-06	1	2.4
2021-05-06	1	2.4
2021-05-06	2	2.4
2021-05-05	2	3
2021-05-05	3	3
2021-05-05	1	3
2021-05-05	4	3
2021-05-05	5	3

I'm trying to use:

Daily Avg = 

calculate(AVERAGE("Sample Table"[Price]),"Sample Table"[Date]), but output is the hourly price for each row, instead of the average.

Any clue on this, please?

Thanks in advance.

Best regards

Hi @Anonymous 

take a look at the following solution:

Average by Day = 
CALCULATE ( AVERAGE ( 'Table'[Price] ), ALLEXCEPT ( 'Table', 'Table'[Date] ) )

@Anonymous , Try a new column like

averageX(filter(Table, [Date] =earlier([Date])),[Price])
