How to Calculate Percentage of Rows With Specific Value in Column?

[Anonymous]

I have a set of data that has thousands of rows. There is a column that lists a rating of "At/Above Average". How would I create a measure that calculates how many rows have the value of "At/Above Average" in columnA and divides that by the total number of rows?

At or Above Average = COUNTROWS ( FILTER(table, table[Column]="At/Above Average") )

Total Rows = CALCULATE ( COUNTROWS (table), ALL(table) )

% At or Above Average = DIVIDE ( [At or Above Average], [Total Rows], 0 )

I followed these instructions exactly and am not getting correct results
