### Estimate using the grid method

With guessing you get an approximate value for a number. With guessing you never count every single object, but only the objects in a selected sub-area. To do this, you divide an image into a grid so that there are roughly the same number of objects in each box of the grid and just count the number of objects in one of these boxes ..
With estimates you can only determine approximate values, so you can never be sure that you have the exact result.

### Estimate with the help of the grid method in the case of unevenly distributed quantities

If the objects in a set that you want to estimate are not evenly distributed, you can still estimate the number with a suitable grid.
With estimates you can only determine approximate values, so you can never be sure of the exact result.

### Appreciate by comparing

If you know the dimensions of a comparable size, you can estimate the dimensions of another size by comparison.
With estimates you can only determine approximate values, so you can never be sure of the exact result.
