How to extract data from raster map to polygon shapefile attribute table

Question

Just as the title says - how do I extract the (average) data from a raster image onto a polygon overlay?

In the attached image, the black square polygons belong to one shapefile. I want to extract the averaged data from the colored raster underlay and apply that average value into a new field in the polygon attribute table.

Anyone with suggestions on how to do this?
