4.3 Quadrats samples




quadrats are use for sampling the distribution of organism in their habitat

and use the quadrat to find the population of daisy:
by random sampling
--> reduce the biasness
- use random number for x,y
- count the number of daisies in the square that was chosen

we need a representative sample - the bigger the better
- looking at about 10 quadrats / 10% of the actual area 

after finishing we create a column


and then we will no the number of daisys per meter squared
