Distribution of sample based estimations of deforestation for Bolivia with 10% sampling intensity. Left: a wide range of estimated deforestation figures is produced when the original 41 Landsat scenes are taken as population. However, when these 41 images are simply 30 times copied (thus generating a much larger population but with exactly the same characteristics like mean and variance), then the 10% sample produces considerably much more precise results!
