Average over attributes

Hi again,

I have another problem and hope for some help:
My table has values from difference sources. All attributes have the name [value]_[reference]. I would like to average over all attributes belonging to the same [value]. Is this possible using the "Loop over Attributes" Operator or any other way? The References are names (strings) by the way.

Thanks in advance.

Best regards,
