Hi Steve, Actually you may be able to do what you want by the "Join by location" plugin which can do group summaries. See Vector --> Data Management --> Join attributes by location.
Another route would be the "Spatial Query plugin" which lets you select points inside a given polygon. With that selection you can assign the polygon value to the points and then use the "Group stats" plugin. However, this is a lot of manual work assigning the polygon information to the points.
