Which method has been used to calculate the mean of output values like precipitation,water yield in mm from sub-watershed to watershed level?

    Hi Manas, 

    I'm assuming that you are talking about the fields of the attribute table ("watershed_results" ) in the water yield model.

    The "mean" values in these fields are arithmetic average of all the pixels comprised within the watershed or subwatershed boundary. 
    Therefore, if you have a watershed comprised of several subwatersheds, the average of the subwatershed values weighted by their areas will give the watershed value.

    Best,
