How alpha diversity metric (all groups) is calculated?

[Eman (Eman Khalaf)]

Hi,

When calculating any alpha diversity metric, we get a single value for each sample, plus Kruskall-Wallis (pairwise) p-value which is between groups. I am wondering what are the calculations done to get such a single p-value (between groups)? Also, can I use it when comparing groups to show the effect of a specific treatment (e.g., healthy group vs diseased group)

Best regards

Hi @Eman,

All groups is also a kruskal wallis test. You can absloutely use it to compare two groups.

Best,
