Gurus,
I have 3 columns in the table. Month-Year, Conversion % and Aggregated Average %.
so if for July 2014, Conversion % is 20% and for Aug 2014 60% and for Sep 2014, it is 70%;
then the Aggregate Avg for Jul 2014 would be (20/1 = 20 %); For Aug 2014, Aggregated Avg would be ((20+60)/2=40%); And for Sep 2014, Aggregated Avg would be
((20+60+70)/3=50%). Once this reaches 6 months, then from next month this should be fixed as a past 6 month average (including current Month) going forward.
Any suggestions would be most appreciated. Please check the JPG for a clear understanding of the issue. Thanks again!
Cheers,
RCC
