How to calculate the average distance to a feature?

Discussion created by kraboo on Jan 22, 2013
I have a point feature class of waste bins and I would like to know the average distance (Euclidean) to each bin.
I have created areas of influence for each point (Thiessen) in order to assign the population to its nearest bin.
Now, I'd like to know what is the average distance to the bin if you are at any point inside its associated Thiessen (I know I am assuming the population can be anywhere inside the Thiessen and they can walk through walls but anyway).

Any ideas?

Thank you!!!
