hello,
User 01/08/2018 - 07:50
I need to calculate a rolling 4 week average in a pivot table
Excelchat Expert 01/08/2018 - 07:50
Hello!
Excelchat Expert 01/08/2018 - 07:50
Welcome to got it pro!
User 01/08/2018 - 07:50
similar to the (% difference from previous week function)
User 01/08/2018 - 07:51
except it needs to be % difference from previous 4 week average
Excelchat Expert 01/08/2018 - 07:51
Sure.
User 01/08/2018 - 07:51
it needs to be within the pivot table not calculated off of the pivot table
Excelchat Expert 01/08/2018 - 07:51
Could you show me some sample data?
User 01/08/2018 - 07:51
so a calculated field of some sort within the pivot
Excelchat Expert 01/08/2018 - 07:51
Sure
Excelchat Expert 01/08/2018 - 07:52
Let's see how to do it
Excelchat Expert 01/08/2018 - 07:53
So you want the percentage of?
User 01/08/2018 - 07:53
% difference from previous 4 week rolling average
User 01/08/2018 - 07:54
It needs to either be an automatic calculation in the table or as a calculated field in the pivot
Excelchat Expert 01/08/2018 - 07:54
ok I see
User 01/08/2018 - 07:55
but this is a sample dataset
Excelchat Expert 01/08/2018 - 07:55
Sure
Excelchat Expert 01/08/2018 - 07:55
What is D5 should be in this case?
User 01/08/2018 - 07:55
my dataset is much larger and is connected by an access connection
Excelchat Expert 01/08/2018 - 07:55
Sure
Excelchat Expert 01/08/2018 - 07:56
what is the value in D5?
User 01/08/2018 - 07:57
It needs to be done through a calculated field or some type of access query
Excelchat Expert 01/08/2018 - 07:57
Ok
User 01/08/2018 - 07:57
ive been trying to figure this out for quite some time and have narrowed it down to that
Excelchat Expert 01/08/2018 - 07:57
So far, I think the best way to do this is go through this way
Excelchat Expert 01/08/2018 - 07:58
And then create another column for percentage calcualtion
User 01/08/2018 - 07:58
no
User 01/08/2018 - 07:58
i am running a pivot based off a table connection
User 01/08/2018 - 07:58
I dont have an actual table to manipulate
User 01/08/2018 - 07:59
unless its manipulating the table within access
Excelchat Expert 01/08/2018 - 07:59
Yes
Excelchat Expert 01/08/2018 - 07:59
I think that the easiest way to do so
User 01/08/2018 - 07:59
so this will be done in access?
Excelchat Expert 01/08/2018 - 08:00
Yes. it will be easier
User 01/08/2018 - 08:00
ok how
Excelchat Expert 01/08/2018 - 08:00
I have tried to use pivot table
Excelchat Expert 01/08/2018 - 08:00
But even in pivot table, it is still the save to manully inseert another column for rolling average and percentage calculation
Excelchat Expert 01/08/2018 - 08:01
So, eseentially that will be the same
User 01/08/2018 - 08:01
so how do I add the rolling average in access
Excelchat Expert 01/08/2018 - 08:02
Wait. In excel, there might be a way to do this
Excelchat Expert 01/08/2018 - 08:02
To calculate a moving average, first click the Data tab’s Data Analysis command button.
Excelchat Expert 01/08/2018 - 08:02
When Excel displays the Data Analysis dialog box, select the Moving Average item from the list and then click OK.
Excelchat Expert 01/08/2018 - 08:03
find the data that you want to use to calculate the moving average.
Excelchat Expert 01/08/2018 - 08:03
In the Interval text box, tell Excel how many values to include in the moving average calculation.
Excelchat Expert 01/08/2018 - 08:03
Then tell Excel where to place the moving average data.
Excelchat Expert 01/08/2018 - 08:03
After you finish specifying what moving average information you want calculated and where you want it placed, click OK.
User 01/08/2018 - 08:06
i cant find a data analysis button
User 01/08/2018 - 08:06
nvm
Excelchat Expert 01/08/2018 - 08:07
Can you find from your local MS excel?
User 01/08/2018 - 08:07
it doesnt allow for a dynamic average
Excelchat Expert 01/08/2018 - 08:07
is there any error msg?
User 01/08/2018 - 08:07
if I add another week to my pivot i will have to recalculate
Excelchat Expert 01/08/2018 - 08:08
can you include a larger range?
User 01/08/2018 - 08:08
no
User 01/08/2018 - 08:09
i need for it to be built in to either the pivot as a calculated field or as an access query\
User 01/08/2018 - 08:09
the solution you provided is a manual fix not an automatic calculation
Excelchat Expert 01/08/2018 - 08:10
Yes since from excel level this is the only way to do so
User 01/08/2018 - 08:10
Excelchat Expert 01/08/2018 - 08:10
If you need a automatic way to do this, you may need to consider access
Excelchat Expert 01/08/2018 - 08:10
Since this is a excel platform, we really not be able to assist with access portion
Excelchat Expert 01/08/2018 - 08:10
We do apologize for this inconvience
