Calculate the Average of Running Difference

[mabryanjr]

I have data that looks like this:

Week Ending	Count	Moving Range	Avg MR
2021-09-18	235
2021-09-25	223	22
2021-10-02	211	12
2021-10-09	218	7

I can get the running difference using the fabs and above functions:

fabs(Column(1) - Above(TOTAL Column(1)))

What I am trying to accomplish is to have the data in the Avg MR column equal 13.67.  (22+12+7)/3

My approach so far has been to use an aggr average on the Moving Range, but it only returns null values.

avg(total aggr(fabs(Column(1) - Above(TOTAL Column(1))), [Week Ending]))

Any help is much appreciated!

Hi @mabryanjr ,

you could use RangeAvg :

1) Label your measure fabs(Column(1) - Above(TOTAL Column(1))) as "Dif"

2) Add new measure, name it "Average" and set expression  RangeAvg([Dif],above([Average]))
