he there,

does anybody have an idea how to reduce the following list efficiently?
A B C
1 a 9
1 a 5
1 a 2
1 a 4
1 a 8
1 b 5
1 b 8
1 b 6

so I want to reduce the columns to
1 a mean(C1:C5)
1 b mean(C5:C...)

tanks
regards
neuerchief

Hi,

If you want to calculate group mean based on group column B, you can try the following:
1. Highlight Col(B), select from menu Worksheet:Remove/Combine Duplicated Rows..
2. In the dialog, set Merge Duplications by to Average. Set Output Worksheet to <New>, click OK.

Thanks,
James
