Analysis scenario

Hello,
I'm relatively new to Power BI and am struggling with an analysis scenario and wondering if anyone has a suggestion on how to handle it.
I've detailed my calculation steps below which are based on sample data. The real data has thousands of records for each year.

Cumulative total tariff points
Any suggestions on how to handle this would be appreciated.
Many thanks
Geoff

    Hi GCC 

    You may try below measures.

    Step1 = COUNTROWS(FILTER(ALLSELECTED('Table'),'Table'[Year]=MAX('Table'[Year])&&'Table'[School]=MAX('Table'[School])))
    Step3_rank = RANKX(FILTER(ALLSELECTED('Table'),'Table'[Year]=MAX('Table'[Year])&&'Table'[School]=MAX('Table'[School])),CALCULATE(SUM('Table'[cum_total_tariff_pts])),,ASC,Skip)
    Lowest 20% avg = CALCULATE(AVERAGE('Table'[cum_total_tariff_pts]),FILTER(ALLSELECTED('Table'),'Table'[Year]=MAX('Table'[Year])&&'Table'[School]=MAX('Table'[School])&&[Step3_rank]<=[Step1]*0.2))
    Middle 60% avg = CALCULATE(AVERAGE('Table'[cum_total_tariff_pts]),FILTER(ALLSELECTED('Table'),'Table'[Year]=MAX('Table'[Year])&&'Table'[School]=MAX('Table'[School])&&[Step3_rank]<=[Step1]*0.2+[Step1]*0.6&&[Step3_rank]>[Step1]*0.2))
    Top 20% avg = CALCULATE(AVERAGE('Table'[cum_total_tariff_pts]),FILTER(ALLSELECTED('Table'),'Table'[Year]=MAX('Table'[Year])&&'Table'[School]=MAX('Table'[School])&&[Step3_rank]>[Step1]*0.2+[Step1]*0.6))

    Hi GCC 

    You may try to create measures as below:

    Step1 = COUNTROWS(ALLEXCEPT('Table','Table'[Year]))
    Step3_rank = RANKX(ALL('Table'),CALCULATE(SUM('Table'[cum_total_tariff_pts])),,ASC,Skip)
    Lowest 20% avg = CALCULATE(AVERAGE('Table'[cum_total_tariff_pts]),FILTER(ALLEXCEPT('Table','Table'[Year]),[Step3_rank]<=[Step1]*0.2))
    Middle 60% avg = CALCULATE(AVERAGE('Table'[cum_total_tariff_pts]),FILTER(ALLEXCEPT('Table','Table'[Year]),[Step3_rank]<=[Step1]*0.2+[Step1]*0.6&&[Step3_rank]>[Step1]*0.2))
    Top 20% avg = CALCULATE(AVERAGE('Table'[cum_total_tariff_pts]),FILTER(ALLEXCEPT('Table','Table'[Year]),[Step3_rank]>[Step1]*0.2+[Step1]*0.6))

      Hi Cherie,

      Thank you very much for creating this code for me and it works just perfect as long as you're working with just one year. I have data for numerous years and numerous schools within these years. I need to be able to calulate the lowest 20% average, mid 60% average and top 20% average for each school within each year. Could you help me with creating this code? I've tried using your code with slicers but it didn't work.

      Thanks once again for your help.

      Regards

      Geoff
