Moving Average in Power Query
I need to calculate the last 4 quarters averages in power query. I know how do rolling average in DAX, but I need to create a column within power query to reference in a conditional format. I'm relatively a beginner in power bi, please give me any advice on how to go about this. I created a new column and put this in:
= Table.AddColumn(
#"Removed Columns14",
"Average",
each if [#"Rank"] > 3 then List.Average(List.Range(#"Removed Columns14"[#"Prevalent Home "], _[#"Rank "] - 3, 3)) else null
, type number)
However, the calculations are incorrect any help would be greatly appreciated. Unfortuntely, I can't provide you with the dataset or the chart, it contains sensitive information.
