I currently have a matrix where the cells represent averages of values. But the request now is to use "root mean square" (RMS) as the aggregate. Since that's not one that Power BI offers out of the box, I'm wondering the most straightforward way to implement it. To clarify, RMS is the square root of the average of all the contributing values squared.

Hi, @bvy , it's straightforward,
Measure RMS = SQRT(AVERAGEX(tb, tb[Value]^2))
Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension! |
DAX is simple, but NOT EASY! |
