In odoo 8, how to calculate average for a field in tree view?
I tried,
<field name = "average_rating" avg="Average"/>
but no change. How to use it?

try "sum" instead "avg"
or
You need to define the field group_operator that by default is sum even if you don't specify it. That it's defined directly in the field, like:
count = fields.Integer('Count', group_operator='avg')
I used group_operator in field ,Still no change. Thanks
group_operator work only when you group by on any field in list view.
