Moving Average

I have a table called drugs with columns drug and result, how do I calculate the moving average of the result column by taking the first 4 rows followed by the next 4 rows and similarly continue. Pfa the sample table for reference.

Re: Moving Average

The formula to use is

If( Mod( Row(), 4 ) == 0,
	Mean( :Result[Index( Row() - 3, Row() )] )
)

I have attached your example data table, with a new column with the formula in it

Re: Moving Average

Do you have 4 columns of results, or 4 times as many rows as you show in your sample data table?

Re: Moving Average

I want to generate the moving average column as shown in the attached table, for every 4 rows I need to calculate the average

Re: Moving Average

Thanks Jim!

 

Just used this method to calculate the difference between the maximum and minimum for the last n rows.

Hope you are doing well!

I think this will give you the moving average that you want (4 rows before and 4 rows after).
