Comparing RMSE for number of of interpolations

[RaziehZandieh]

Hello, I have air quality data and I need to interpolate them. The points (samples) are distributed in grid pattern and the distance between them is 1000 meter. I'm not familiar with Arc GIS and I don't know which type of interpolation I should use. I was told that I should use different types of interpolation and then check their RMSE. Can you explain me how I can check the RMSE of interpolations in Arc GIS? I think the lower RMSE is the better. yes?

In ArcMap open the Geostatistcal Toolbar > Geostatistcal Wizzard that will guide you through the interpolation. But first explore the data and refer to the help or tutorial offere by the same toolbar. Usually Kriging method returns satisfying results and RMSE as I can remember.
