How to apply a column formula on only a range of rows and not every row?
Hi, I am trying to create a column formula that calculates the mean of every 5 rows (for a specific column). Normally the formula are applied to every row using values in such row. Instead, I would like to use values from 5 previous row to calculate a mean value. I am been playing with the formula editor and try to use the Row() and other functions, but without success. Thanks a lot to anyon...
