Midwest | And to keep the first post from turning into an essay, I'll start number 2.
When you run a normalization you'll also get CV values. (coefficient of variation) Google will tell you more than you'd ever like to know about it. It measures how consistent the values were for each square. In my earlier example, the 92, 94, 96 would be very consistent and have a very small CV. (0.02) My other example would have a higher value meaning they are more inconsistent. Higher the number, more variation.
These values have NOTHING to do with actual yield or whatever you're normalizing. Values of 2, 4, and 6 in my 0-100 scale would have a CV of 0.02 as well. They are consistent, just like the 90's example. You need to look at the CV map and normalized yield map together to find consistently high, consistently low, etc areas. | |
