Tutorial 5 Worksheet  Figure of Expected Results – Option #2 Observation: More deciduous trees have been cut than coniferous trees. Hypothesis: More deciduous trees have been cut down than coniferous trees because branches are lower to the ground on conifers making it harder for the beavers to access the trunk of the tree in order to cut it. Prediction: If the beavers don’t choose the conifers because of their low branches, then if the low branches are removed they will choose more conifers. Experimental unit: Plots with a radius of 150 m around a beaver pond in a forest that contains both deciduous and coniferous trees. Treatments: Cutting off branches on the bottom of conifers to a height of 0.25 m, 0.5 m, 0.75 m and 1.0 m Control: Conifer tree with the lower branches not manipulated. Randomization: Assign the treatments and control randomly to the experimental units using a random number generator. Replication: 10 replicates per treatment and control, i.e., 50 experimental units in total (Rule of Ten). Response variables: Number of conifers cut down by beavers. Null hypothesis to be tested: The number of conifers cut down will be the same for trees with and without the lower branches removed....
