P1350011
We want to estimate how many leaves grow on this Birch tree
P1350011-1-square
We choose a sample area of leaves, and mark it
P1350012
A close-up of the sample area of leaves
P1350012-2x5-grid
The sample is divided into ten parts
P1350012-120-leaves
We count 120 leaves in one part - so guess 1,200 in the sample
P1350011-64-squares
64 samples of 1,200 means 76,400 leaves in this picture
P1350011-copy
There could be a million leaves on this tree!
