Find Average for another column

Hi,

I'm trying to find the average of event attendees for each category. Example: average for Category 1 would be 19.5 (15+24/2)

Attached is an example of the table data that I have right now.

How would I go abouts calculating the average

Thanks

    Hi Pillz,

     

    Given your Data Model I think the following will work

     

    % By Category = 
var numerator = CALCULATE(COUNTROWS('Data'), ALLEXCEPT('Data','Data'[Category]))
var denominator =  CALCULATE(COUNTROWS(SUMMARIZE(ALLEXCEPT(Data, 'Table'[Event Category]), Data[Event], "m", COUNTROWS(Data))))
 return 
divide(numerator,denominator)

    Hope this Helps

    Write a measure like this

    Avg Attendees = AVERAGE ( YourTable[Attendees] )

    Then add your [Event Category] and the measure to a matrix visual.

      Thanks for the response,

      Actually the attendee column is just a COUNT of Table[Attendee Name] rather than a hard number value. Would that change the approach of my problem?

        Please share the layout of your data model so we can understand the tables involved and also any measures you are using and how they are getting calculated.

    Pillz , In case you need column

    avergageX(filter(Table,[event category] = earlier([event category])),[attendees])

    Hi Pillz 

     

    I think this Measure will work for you

     

     

     

    % By Category = 
var numerator = CALCULATE(SUM('Table'[Attendees]), ALLEXCEPT('Table','Table'[Event Category]))
var denominator =  CALCULATE(COUNTROWS('Table'), ALLEXCEPT('Table','Table'[Event Category]))
 return 
 DIVIDE(numerator,denominator)

     

     

     

     

     

    Hope this helps,
