===Method===
Estimate the population of a species within a habitat using random sampling.
#Gently throw Place a quadrat to fall in a random position on location in a field . (''Exam boards apparently do not allow throwing of the quadrat, even though this would reduce bias in the choice of grasssample space.'')
#Count the number of daisies within the quadrat.
#Repeat steps 1 and 2 ten times.
#Repeat step 2 six times moving the quadrat 5m further along the transect each time.
#At each location you may measure the light intensity, soil hydration or soil [[pH]] to determine if this factor affects the abundance of daisies.
