Estimate the size of a [[population]] of a [[species]] within a [[habitat]] using [[Sampling (Biology)|sampling]] techniques and investigate a factor affecting [[population]] size.
===Method===
*[[Independent Variable]] - Investigate the population of a species within a habitat using random sampling.*[[Dependent Variable]] - #Gently throw a quadrat to fall in a random position on a field of grass.#Count the number of daisies within the quadrat.*[[Control Variable]]s - #Repeat steps 1 and 2 ten times.#Calculate the mean number of daisies.#Use the following equation to estimate the number of daisies in the field:: Estimated population = <math>\tfrac{area sampled}{total area}</math> x number of daisies
