I have some points feature and I want to get rid of some 'noises' by putting them in the boxes and averaging their values.
Can anyone give some ideas how to do this in ArcGIS?
Solved! Go to Solution.
I guess you missed this part in the help topic
geometry_type (Optional) | Determines if the output fishnet cells will be polyline or polygon features.

create a fishnet if you are working in vector world, then you can Finding what is inside a polygon—Help | ArcGIS for Desktop checking what you want to field you want to summarize on and what stat you want to return but for better control you can use Spatial Join—Help | ArcGIS for Desktop but pay attention to field mapping to ensure you get the information you need for summarizing.
Best option if it must be a rectangular grid. What is your opinion on using a hexagonal coverage "grid"? I like the way it smooths the distribution visually.
Do I need to convert fishnet into polygon before Spatial Join?

You could also use Focal Statistics—Help | ArcGIS for Desktop on the resulting raster after interpolation. Choose an appropriate grid window (3X3, 5X5, etc.) and Statistics_Type = "MEAN"
