Divide Row Value with a measure

[Anonymous]

Hi everyone,

I have a survey which can be completed by several people from the same company. I want the average score per category and this is done by taking the value in the score column and dividing it by the number of people who filled out the survey from the company. 

However, the company participant count is a measure which has been calculated using the following:

COUNTROWS(FILTER('Survey Responses','Survey Responses'[Company Name] IN VALUES('Section_Summary'[Company Name])))

as number of people from a particular company is located in a different table.

I have the following table,

Company	Score	Category	Company Participant Count
ABC	129	Cat1	3
ABC	103	Cat2	3
XYZ	36	Cat1	1
XYZ	26	Cat2	1

Ideally I want to add another column (measure or calculated column otherwise) that takes the value in the score column and divides it by the value calculated using the company participant count measure?

Thank you in advance!

Hey, so I used the measure you gave to recreate my static score column as a measure which I then divided by the measure for my participant count column and this has worked! I hope this was the intended use - Thank You!

If its not too much bother can you explain why the measure you provided calculates a row wise average for the score across company and category? I struggle a lot with PBI contexts at the minute 😕

Sure.  The ALLEXCEPT function removes all the filters from the columns of the specified table except the the ones you list.  The table visual provides filters on Category and Company because you added those columns to the visual, and the measure removes filters from any other columns you've included (e.g., Score, if not aggregated).

Here is a measure expression you can try

Avg for Company and Category =
CALCULATE (
    AVERAGE ( Table[Score] ),
    ALLEXCEPT (
        Table,
        Table[Company],
        Table[Category]
    )
)
