weighted average for a month

Anonymous — Wed, 15 Jun 2022 09:03:30 GMT

Hi guys, I have a problem with my measure,

I would like to do a progressive calculation. That is to say I have three columns, one with the number of session, one with the average time per session and another with the cumulative number of session each month.

Starting from a date, I would like to calculate a weighted average on a month period. For each day from the date I started to the last month, i want to divide the number of sessions of each day by the cumulative number of session each month equal to the DAY I STARTED. The total multiplied by the average time per session.

DIVIDE( CALCULATE ( SUM ( 'Google analytics'[Number of sessions] ) * SUM ( 'Google analytics'[Average time per session] ), DATESINPERIOD ( 'Google analytics'[Date].[Date], FIRSTDATE ( 'Google analytics'[Date] ), -1, MONTH ) ), SUM ( 'Google analytics'[Cumulative number of session each month] ) )

To give you an exemple I am giving you this excel:

I want to calculate the session time weighed average for the DAY 6, so i have to sum all the session time weighed average of all other days. To calcul them, i am using the last cumulative number of sessions.

I hope you can help me, tell me if i'm not clear enough.

Hi， Anonymous

It is necessary to first judge whether the results returned by the numerator and denominator are correct.

Can you share a sample file for further investigation?
