I am very new to ArcGIS and I am having what seems to be a simple problem that I can't seem to figure out. I am trying to do a kriging of precipitation data. I am using ArcGIS 10.2.There are 9 rain gauges which I have displayed the xy data via a spreadsheet. The spreadsheet has 4 columns where one of them is "precipitation'. The input are the data points, precipitation is the z, and everything else i left as default. However when the output results are generated I get a range of 40.47-40.48 (kriging_shee1)for the rainfall. Another hint or insight in the problem is when i made a similar spreadsheet with the values ranging from 2-7 inches of precipitation the kriging worked. It is whenever I change the precipitation values to higher values I seem to get more of an average value, not the range. Enclosed is a jpg which provides insight. Thank you for any help if anyone can figure this out.[ATTACH=CONFIG]28632[/ATTACH]
