Calculating averages using point data: Desperate for assistance!!!!

Hi,

I currently have a global map shapefile, superimposed by 8192 data points that show temperature changes (per degree Celsius of global warming) and degrees of latitude/longitude at those locations on the globe. So, for instance, an individual data point would say (when using the "Identify" function) at 180 West, 45 degrees North, the temperature change per degree Celsius global warming is 0.8 Celsius. Each of the 8192 points contain this sort of data.

What I am attempting to do is simply calculate various averages for different regions by somehow combining the necessary points over those regions. For example, if I would like to calculate the average temperature change in the United States, how could I do this using the point data that covers the United States?

Any assistance would be greatly appreciated!

Patiently awaiting your response(s),
