Getting an average total in a poll

[Existant]

Greetings all,

I was wondering if there was a mod or a way to get an average total from a poll?

For example; I am making a video game section in the off topic of one of my boards.  I would like the members to be able to go in to a game discussion, and there be a poll up top like a normal poll, rating from 1 to 10.  And once they vote, it shows a running average to one decimal point.  So if five people vote 7 and one votes 6, then the average 6.8 is displayed.

Can this be done?
