If an experimental design includes systematic variation it means that: O Changes in only one dependent variable are being observed and recorded. O Across experimental units, independent variables are changed in such a way that the separate effects of each can be discerned. O Any confounding variables, which may influence the outcome of an experiment, are held constant. The experiment is repeated to ensure conclusions aren't drawn from a single unusual result.

QUESTION 4 a. i. The capture and release method (Lincoln index) is used to estimate the size of a population. List TWO assumptions that are made, when utilizing this method. ii. To estimate the population size of rats mark and recapture exercise was conducted. 150 of the animals were randomly captured and tagged in the first sampling effort. After four weeks a second sampling effort was carried out during which 110 rats were caught, 50 of these possessed tags given in the first sampling. Use the Lincoln index equation to estimate the population size of rats in Bridgetown Bridgetown, a iii.
