I have an experiment to look at habitat preferences of beetles and the effect of competition. In the first test, a beetle is on his own in an arena and I measured the % of time he spends in each of THREE types of habitat (open, bush and underground). I repeat this experiment with several beetles. In the second test, beetles are placed together with a beetle of a competing species in the arena and they are again observed for their % time in each habitat.
I want to test if the amount of time spent in each habitat is affected by the presence of the competitor.
But how can I compare the % time in each of the three habitats when the competitor is absent (test 1) and present (test 2)? Which test can answer this question? Do I need to test the means?
My expectation is that in the presence of the competitor the use of Habitat 2 would increase.
Apologies, I dont know how to import data.
