I would like to perform STDEV.P calculation based on criteria in one column.
My current formula is:
{=STDEV.P(IF(Aggregated!Y$15:Y$3000="*cta*",Aggregated!AD15:AD3000,""))}
E.g. the case of AVERAGE(IF... is much simpler cos I do not use "=" but instead have "*cta*" as one of the criteria.
The result is #DIV/0!
PS. I face a similar issue with MAX(IF(... where the criteria is "*cta*"
Please advise. Thank you
