Computing error for a map compared to another map

Hey everyone.

I have a MODIS Evapotranspiration map and then I have built my own two Evapotranspiration maps based on two different models. I would like to compute the difference (error) from both these models to the MODIS ET map.

How do I do this is Arcmap 10.1?

Sorry for asking this rather simple question, I have tried to search for a solution but so far I havent found exactly what I am looking for. Most of it is only related to statistics for the single map, while I want a comparison between maps.

Thank you very much, very appreciated.
