Dear All,

v. ArcGIS 9.3

I would like to know what is the difference between the standard deviation in the attribute (Right click on the attribute name -> Statistics) and the standard deviation from the layer properties (Properties -> Symbology -> Classified -> Choose Field Value -> Classify -> Classification Statistics)

So if one asks me to give the standard deviation, let's say of my temperature data (raster), which one should I provide?

Thank you,
