The Calculate Point Statistics tool takes an input Polygon and Point feature class and uses a selected field to find the minimum, maximum, and average of the points and adds the results to the polygon feature.
Be sure to view the Tool Help within the tool dialog box for detailed instructions. Also, check the Geoprocessing Results for any error messages.
I hope someone finds this tool useful. If you’d like this tool to calculate additional statistics for the points, let me know. Please leave a comment if you have any questions or problems, and be sure to check out the other tools I’ve created!
