Quadrates samples

4.3 describe the use of Quadrates as a technique for sampling the distribution of organisms in their habitat.

We need to find the population of daisies:

Sample needs to be - Random (to avoid bias)
                               - Representative (Large enough) We need this and usually the bigger, the better.
                                  about 10 quadrats must be placed or 10% of the area.
After you add up the number of daisies per meters squared in each Quadrat and divided it by the number of Quadrates.

this will give us the value which is the number of daisies per meter square.
You can also you this technique to compare the number of a species in different areas.
