Calculate median for different groups
Hi,
I have a file with data and some months on, the months are as numbers, e.g. jan =1 , feb =2, . I would like to be able to calcule the mean values based on data in col a by month in col c. It would be good if i could have just one formula that looks at the records in col c and if it is say 1, than looks at the value in col and then returns the median ov all records where colc is 1, then I could do the same for the other months. Hope this makes sense, Cheers Daniel |
Median or mean? Median for Jan.:
=MEDIAN(IF(C1:C100=1,A1:A100)) Array-entered, meaning press ctr/shift/enter.

I suspect you'll ultimately be happier if you use a Pivot Table, which
can show the mean values for all months simultaneously: http://peltiertech.com/Excel/Pivots/pivotstart.htm But for an individual month you could use (array-entered): =AVERAGE(IF(A1:A100=1,C1:C100,"")) In article , "Daniel" wrote: Hi, I have a file with data and some months on, the months are as numbers, e.g. jan =1 , feb =2, .
