Calculating Averages in a chart

Wed, 11 Dec 2013 19:54:13 GMT

Hi all, Posted this earlier but wasnt very clear. I have to calculate an average but remove the last value by date i.e. 1/5/13 to the 1/6/13 so remove the value associated with the 1/6/13 and then calculate the average. This can happen mid month so it is always the latest value by date that is removed.

sum(Amount)/Count of Date less 1

Below is an example

01-May	500	500
02-May	500	500
03-May	200	200
04-May	700	700
05-May	700	700
06-May	700	700
07-May	700	700
08-May	700	700
09-May	700
Actual average	600	587.5

Can someone tell me how I do this with Set analysis

I can get the count working but cant get the sum to work. Does anyone have any ideas?

Thanks

Alan

Thanks for your help, however the the first column of dates would be all that was in the QV the second column is an example of how i want to calculate the average. i.e I want to sum all but deduct the value with the corresponding latest date and then calculate the average. using a count - 1.

Date	Value
01-May	100
02-May	150
03-May	150
04-May	150
05-May	150
06-May	150
07-May	150
08-May	150
09-May	150
10-May	200
11-May	200
Actual average	154.55
Average I want	150
To calculate the average after removing the last value (in yellow) via script.

The bold value related to 11-May needs to be ignored for average calculation.

Regards

Alan
