Okay, I've spent almost an hour reading everything on aggregating, de-aggregating, resolving "Cannot mix aggregate and non-aggregate arguments" Calculation errors, etc etc etc, but I'm not getting anywhere. I must be missing something!
I'm connected live to an excel spreadsheet. All I need to do is create a calculated field in tableau based on two columns in the excel spreadsheet- square feet and rate. A simple average of the rate won't do, I need it to be weighted on square feet. Rate is just a dollar figure, Square Feet is a number...
Anyways, both field properties shows that both fields are sum aggregations, and they are both measures.
Anyways, without getting into correct syntax:
Sum Rate * Square Feet / Sum Square Feet
Sum Rate * Sum Square Feet / Sum Square Feet
I can't get either of these to work - I have received a number of errors related to aggregated arguments and valid table calculations
Any help would be much appreciated
Thank you!
Hi Carson, here's the one I use - it may just be about brackets?
SUM([Frequency]*[Sample Size])/sum([Sample Size])
