Question
Design 3 experiments to test the null hypothesis that the invasive Argentine Ant (Linepithema humile) has no effect on the abundance of foliage-eating insects on native willows. The first experiment should be a between-subjects design ANOVA, the second experiment should be a within-subjects design ANOVA, and the third experiment should use a regression approach. Outline how you would use preliminary data to decide which approach is best.
Source of Variation df Between Trees Treatment Trees within Treatment 1.020 5.187 17.7 18.0Explanation / Answer
form the given data
it is best to use the ANOVA method of Experiment
here the ANOVA between between trees has P-value less than 0.001(<0.05) hence there is enough evident to reject NULL hypothesis of there is no effect
and also the same with the case of ANOVA of with trees experiment where the P-value is less than 0.0001(<0.05)
Hence the best approach is to use ANOVA than Regression
