Calculate weighed average

Anonymous — Tue, 11 Oct 2022 07:00:31 GMT

I want to make a measure that calculate a weighted average of how many minutes our customers have been actively shopping in our store but I can´t for the life of me figure out how to do this in DAX.

Say I have these two lines

minutesInStore	minutesQueue	Customers
30	5	10
20	10	5

I want to figure out how long time the average customer have spend in my store actively shopping (minutesInStore-minutesQueue)

My normal go-to in SQL would be to make a column calculating the total minutes per line (minutesInStore-minutesQueue)*Customers as customerMinutes)

minutesInStore	minutesQueue	Customers	customerMinutes
30	5	10	250
20	10	5	50

and then the sum of customerMinutes divided by customers (sum(customerMinutes)/sum(customers) as avgMinutes

(250+50)/(10+5)=20

But how can I replicate that in DAX?

Try

Avg Minutes = VAR CustomerMinutes = SUMX ( 'Table', ( 'Table'[Minutes in store] - 'Table'[Minutes In Queue] ) * 'Table'[Customers] ) VAR Customers = SUM ( 'Table'[Customers] ) RETURN DIVIDE ( CustomerMinutes, Customers )
