Webb31 juli 2024 · The Hutcheson t-test is a modified version of the classic t-test that provides a way to compare two samples. The key is the formula that determines the variance of the Shannon index. These notes will show you how to conduct the Hutcheson t-test and so get a statistical significance of the difference in Shannon diversity between two samples. WebbH = ∑ [ ( p i) × l n ( p i)] Where − p i = proportion of total sample represented by species i. Divide no. of individuals of species i by total number of samples.
