I am using the default view Taxonomy term.

I added a "number" field to my article content type.

I would like to obtain the average of the fields of the nodes listed by term of taxonomy.

For example, I have two nodes, which have as fields numbers: 2 and 4, and whose term is common taxonomy: A.

I would like in the view of the term taxonomy A, get the average of the fields "number" of these nodes, namely 3.

I tried views aggregation, add two fields: a field of type "Content: title", with aggregation: Group together, and a field of type "AVG (Content: Note)", with aggregation: "Average".

But it does not work.

I tried to add different relationships, but without success.

Someone would know the right configuration of views to do that? Thank you
