Calculate Average for Common Columns in Matrix

I would like to calculate the average of the baseline assessment for just the common standards. In this case, it should be the average of 7.1, 7.2 and 7.3. I would also like to calculate (nonbaseline...

Hi tylerr2142,

I also think share some same data will help us clarify your data structure and test to coding formula.

In fact, we do not need the real data, you can keep the raw table structure and build some dummy data to share. (e.g. use random value to replace the raw numerical values, replace sensitive string with test,123...)

BTW, where did these common standards from? Based on calculations or specific by filters?

The data structure looks like the below:

UsernameAttemptDateExamSectionScore
Sally1/1/2020Baseline1.150%
Sally1/1/2020Baseline1.225%
Sally1/1/2020Baseline1.3100%
Sally1/1/2020English 1011.175%
Sally1/1/2020English 1011.280%
Sally1/1/2020English 1011.490%
Sally1/1/2020English 1011.795%

 

I want to be able to calculate the improvement from Baseline exam to other Non-Baseline exams with identical sections. (I.E: a score of 50% for baseline section 1.1 to the 75% for English 101 section 1.1. 

 

Thanks for the help!

    Hi tylerr2142,

    Did you mean you want to calculate the average 'Score' across multiple exams based on the most general 'Section' which existed all exams, right?

    If that is the case, you can try to use the following measure expression to replace the scope field to use in matrix and confirm if it works on your side:

    Measure = 
VAR currSelection =
    MAX ( 'Table'[Section] )
VAR _list =
    CALCULATETABLE (
        VALUES ( 'Table'[Section] ),
        FILTER (
            SUMMARIZE (
                ALLSELECTED ( 'Table' ),
                [Username],
                [AttemptDate],
                [Section],
                "cExam", COUNTA('Table'[Exam])
            ),
            [cExam] >= 2
        )
    )
RETURN
    IF (
        currSelection IN _list,
        CALCULATE (
            AVERAGE ( 'Table'[Score] ),
            ALLSELECTED ( 'Table' ),
            VALUES ( 'Table'[Username] ),
            VALUES ( 'Table'[AttemptDate] ),
            VALUES ( 'Table'[Section] )
        )
    )
